You may be the smartest person you know, but how are you when it comes to having some common sense or solid knowledge of the most common of facts? We're not just talking about street smarts here; we're talking about having an all-around intelligence that can not only get you out of a bind but can destroy the competition in a casual bar quiz. Whether you're a math whiz or you're good with your hands, we're going to put you to the test! And we're not talking about the kind of test you used to master in school.
From knowing which country in the world has the highest population to understanding a little bit of simple grammar, or having a quick mind if you're injured to being aware of what you should not feed your dog, there is a whole universe of knowledge out there that only someone with the mind of a Jedi would know. However, we're willing to bet we've snuck some questions in here that will stump even the most brilliant of you.
So, smarty pants, do you have what it takes to ace this quiz on common facts? Let's find out if that mind of yours is that of a Jedi after all!
The term"e.g." is used in sentences quite often, but do you know what it actually means?
E.g. stands for "exempli gratia," which means "for the sake of example." It can also more easily be remembered as "example given." Many writers have mixed e.g. up with i.e., which is an abbreviation of "id est" and translates to "that is" or "in essence."
Humans can be allergic to just about anything, especially animals. But what animal is sometimes allergic to them?
Cats will sometimes get seasonal allergies to pollen and grass, but every so often there is a cat who actually will have a reaction to their human. This isn't a common occurrence since humans bathe much more frequently and don't shed nearly as much dead skin or hair, but it still happens! More often than not, it's caused by residue from perfume, soap or detergent.
The sun rises in the _____ and sets in the _____.
Everywhere in the world, the sun, moon, planets and stars will all rise from the east and will set in the west. It may slightly change with its exact location from day to day, but no matter what it'll always be in those directions due to the Earth's axis. Fun fact: Venus rotates its axis the opposite way that Earth does, so that means that the sun rises in the west and sets in the east there.
This is a tough spot ... you're injured but don't have proper medical equipment. What can you use to disinfect the wound?
Aside from it's more obvious uses, alcohol does have the ability to kill germs and disinfect wounds. While it may delay the healing process, if you do not have proper first aid or medical equipment, but you do have a bottle of booze, you'll want to use it to clean the wound and any equipment you may use in a situation like this.
Everyone wants their doggos to have a healthy diet. What's the one major thing they can NOT eat?
Dogs really shouldn't eat a lot of the foods that humans do, but one of the more important ones to avoid is chocolate. The main reason is an alkaline in chocolate called theobromine; humans' stomachs can easily metabolize it, but a dog's stomach processes it much more slowly, which causes a build-up of toxins in their system. Too much of it can actually kill a dog.
How many times can you take away three from 18?
Just once! While your mind may have gone to multiplication or division first, this is a simple subtraction problem. After the first calculation, you will be subtracting three from 18, then three from 15, and so on.
When did Christopher Columbus sail the ocean blue?
You know the rhyme everyone learned in school! "In fourteen hundred ninety-two, Columbus sailed the ocean blue. He had three ships and left from Spain, he sailed through sunshine, wind and rain." There's more of course, but ain't nobody got time for that!
What is a baby horse called?
The correct name for a baby horse is foal. While it is common (and fun) for people to refer to baby horses as ponies, this is not correct. Ponies are an entirely different breed of super cute, miniature horse.
When buying stocks, always buy _____ and sell _____.
Most should recognize this adage, even if they don't have anything to do with stocks or the market. Basically, this is the practice of buying a stock when its price is perceived to be low and then turning around and selling when it is high. This can be easier said than done, though. Someone doing this must be able to determine market trends and decide when they have the least risk.
Which of these is technically considered a vegetable?
The carrot is the actual vegetable here; it is a root vegetable. Most people know that a tomato is actually a fruit, and that's because grows on a vine. The same is true of cucumbers (bet you'll look at pickles differently now!). Finally, pumpkins are also actually a fruit, and that's because they are full of seeds.
A down comforter or pillow is typically filled with _____.
While some pillows and comforters are indeed filled with cotton, usually, the term "down" means they're filled with fluffy clusters of super-soft feathers that come from ducks and geese. The quality and number of the feathers used will determine how expensive these products will be.
Time to bake some tasty treats! How many eggs are in a baker's dozen?
The term "baker's dozen" comes from the practice of medieval English bakers including an extra loaf of bread when they'd sell a dozen of them. They did this to avoid being penalized for being underweight in their transactions. While this sort of practice isn't really used today, every so often you may come across someone who includes that 13th donut or baked treat just to be nice.
You're running late and need to make a quick breakfast. How long does it usually take to hard-boil an egg?
Twelve minutes is typically the best amount of cook time to get the perfect hard-boiled egg. If you live at a high altitude, you can still use this amount of time but let the water sit at more of a simmer, rather than a full boil. You'll know if you've overcooked it if you notice a green tinge to the yolk and a sulfuric taste when you crack open the egg.
What is the highest mountain in the world?
Mt. Everest is the world's highest mountain by altitude. At its highest peak above sea level, Mt. Everest sits at 29,035 feet. While some other mountains may be considered "taller," this is only because the total vertical distance between their base and their summit is greater.
If a person is stabbed and the object is still in them, what should they absolutely NOT do?
If a person is stabbed and the object is still there, the absolute worst thing you could do would be to remove it. It would actually do even more (up to double) damage than if the object is just left alone and the person is rushed to the hospital. Since the object will have already sliced through tissue, removing it would not only do more damage to the already-cut tissue, but likely tear through even more on its way out.
In your garden, you have 13 basil plants. Lightning strikes and destroys all but five of them. How many plants do you have left?
With this question, you may have first wanted to subtract five from 13, giving you eight. However, if you really paid attention, you would notice the answer was already given to you! Lightning struck, killing all BUT five of the plants, so you still have five left. Easy peasy!
What does a barometer measure?
Weather forecasters use barometers to help them in determining weather patterns as they measure atmospheric pressure. Typically, falling air pressure will suggest that wet, stormy weather could be headed your way, while rising air pressure may mean clear, sunny weather is on the horizon.
You're adventuring around London and need to cross a two-way road. Which way do you look first?
The United Kingdom is one of the few countries in the world who drive on the left side of the road. So if you get the opportunity to go and visit England, be sure that when you are crossing a two-way road you always check to your right first before you cross, since traffic will be approaching from that direction.
Two fathers and two sons go fishing and catch three fish. They decide it's enough food for all of them. Is this possible?
Yep, this is absolutely possible! If there are two fathers and two sons, that would mean that the first father is a dad to the second, and the second father is a dad to the first son, while being a son to the first father. That makes a total of three, with three fish to enjoy!
In the state of Florida, is it legal for a man to marry his widow's sister?
Nope! This would not even be a possible scenario. If you are talking about a man's widow, that would mean that he's actually dead, so he is of course not marrying anybody. Marrying someone after they're dead is not necessarily possible, or legal for that matter in the United States. However, France will practice posthumous marriage if the "couple" provides the proper documentation.
If you're having a heart attack, what is the first thing you can do to help ensure you survive it?
While it won't taste good, one of the best things a person can do if they're having a heart attack is to quickly chew up some aspirin and swallow it. Sure, you could just take it in usual pill form with some water, but it wouldn't go into action as quickly as chewing it up and releasing its active ingredients. Those few minutes could make all the difference!
As humans get older, a part of the body continues to grow. What part would that be?
That's right, you may be fully grown, but as humans continue to age the cartilage in the body never stops growing. You can find this plastic-like material in your ears and your nose. So, everyone can all look forward to some bigger noses and ears in old age. On top of that, the ear lobes can and usually do elongate because of gravity.
What is the best way to cure a virus?
That's the bummer about viruses. There's no quick cure for them, you gotta just rest, take your vitamins and get as many fluids as possible. Antibiotics are used when you have a bacterial infection, like strep throat or a sinus infection. If you try to take antibiotics when you have a virus like the flu, you'll just bring your immune system down.
What does CPR actually stand for?
This is a hard one to remember, but CPR does stand for Cardiopulmonary Resuscitation. This is a technique everyone should know. If a person stops breathing or their heart stops beating effectively, this can save their life and restore oxygenated blood flow to vital organs. One thing that's easy to remember: as you're pressing on their chest, do it to the tune of "Staying Alive" by the Bee Gees.
Which of these is heavier: 75 pounds of timber or 75 pounds of paper?
That's right, it doesn't matter what the material is. If you have 75 pounds of paper and 75 pounds of the very thing it comes from, you will have an equal amount of weight between them, even if it takes WAY more paper to reach 75 pounds than it does timber.
What is the actual color of the blood in human bodies?
Regardless of the amount of oxygen in your blood, it is always red. When a person looks down at their veins, say in the arms, they will either see more of a blue or green color. This is only because of how the skin reflects light. It's still red in there!
What country has the highest population in the world?
Currently, China is the most populated country in the world with a total of 1,389,618,778 people living there. Compare that to the 331,883,986 living in the United States (third most populated), and you have quite a leap in the populous! The least populated country is the Vatican City (it is a United Nations-recognized country) at 451.
How many bones are there in the human body?
Humans have quite a number of bones that make up the body's framework. In fact, a person will have around 270 bones at birth, but as they grow and some of those bones fuse together, that decreases to 206 by adulthood. You'll find a good number of those bones in your hands and feet — there's a lot of small ones that help them move.
You've just bought a goldfish. What's the best vessel to make his new home?
You may usually see goldfish that are quite small, but in reality, these guys can grow to be pretty big. That's why they need as big of an environment as possible to call their home once you bring them into yours. Of course, ponds aren't exactly available to most people, so just be sure you have a large enough tank for them. Never put them in a bowl!
How can you tell what side of the car a gas tank is on without getting out of the car?
You've maybe noticed that your car's fuel gauge has a little arrow pointing to either the left or the right. That little arrow tells you which side your gas tank is on. Hopefully, this will help keep you from pulling up to a pump on the wrong side next time!
How many months have 28 days?
Another fun little trick question for you! February surely came to mind as the one month that only goes up to 28 days (with the exception of a leap year, of course), but if you're talking which months have 28 days, that's all of them.
If you're driving on an icy road and your car starts to skid, what do you do?
Whether you've driven in inclement weather or not, you should know that if you slam on the brakes after hitting ice, you might go into a spin. If this happens, get your foot off the accelerator and onto the brake. Begin to turn your wheel in the direction of the skid gently, and then start to pump your brakes lightly. This should help you regain control of your car.
Oh no! A grease fire! What should you NOT do while trying to put it out?
When you see a fire, the first thing that comes to mind is dousing it with water. In the instance of a grease fire, water may cause it to spread, so don't do this! Instead, cover it with a lid. Or, if you have it handy, baking soda can help smother it.
Last question! What is the beginning of eternity, the end of time, and the beginning of every end?
For the final question, this was hopefully a fun one. The answer is, indeed, the letter "e." Look at the question again, and this will totally make sense. The letter "e" is the first letter in "eternity," the last letter in "time" and the first letter in both "every" and "end."
The smell after it rains really is the best, but what is the actual name for it?
Petrichor comes from the Greek words "petra," meaning "stone" and "ichor," which refers to the flow of liquid. It is used to describe the aroma that comes from rainwater mixing with oils that plants excrete onto the ground. Two Australian scientists were the first to coin this term in 1964.
