1. exempla gratuitous
   exempli gratia
2. example given
   exemplum gracious

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."

1. Dogs
   Cats
2. Parakeets
   Ball Pythons

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.

1. West; east
   North; south
2. South; north
   East; west

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.

1. Water
   Hot iron
2. Alcohol
   Petroleum jelly

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.

1. Blueberries
   Peanut Butter
2. Chocolate
   Lettuce

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.

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.

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!

1. Pony
   Foal
2. Calf
   Doe

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.

1. Slowly; immediately
   Low; high
2. Immediately; slowly
   High; low

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.

1. Tomato
   Cucumber
2. Jalapeño Pepper
   Carrot

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.

1. Fur
   Cotton
2. Feathers
   Wool

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.

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.

1. 20 minutes
   10 minutes
2. 12 minutes
   16 minutes

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.

1. K2
   Denali (formerly known as Mt. McKinley)
2. Mt. Kilimanjaro
   Mt. Everest

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.

1. Take the object out.
   Call 911.
2. Lay down and check pulse and breathing.
   Try to control the bleeding.

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.

1. Zero
   Three
2. Eight
   Five

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!

1. Atmospheric pressure
   Water pressure
2. Weather patterns
   Body temperature

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.

1. Right
   Left
2. Straight ahead
   Behind

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.

1. No
   I'm confused ...
2. Yes
   That's too much food.

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!

1. It's not possible.
   Only if the widow left it in their will.
2. No, it is not legal.
   Yes, it is legal.

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.

1. Hold your hands above your head.
   Chew aspirin.
2. Put a cold compress on your forehead.
   Drink coffee.

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!

1. Tendons
   Muscle
2. Bones
   Cartilage

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.

1. Antibiotics
   Shots
2. Rest and lots of liquids
   Homeopathic methods

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.

1. Cardiopulmonary Resuscitation
   Cardioesophageal Point Return
2. Cardioplegia Pressure Representation
   Cardiovascular Pressure Repetition

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.

1. Timber
   They're equal.
2. Paper
   Neither

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.

1. Blue
   Red
2. Purple
   Pink

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!

1. India
   China
2. Brazil
   United States

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.

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.

1. Bowl
   Tank
2. Vase
   Pond

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!

1. Look in your side mirrors.
   It is always on the driver's side.
2. The fuel gauge has an arrow that points to what side it is on.
   It is always on the passenger's side.

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!

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.

1. Turn gently towards the skid while pumping your breaks.
   Slam on your breaks.
2. Take the keys out of the ignition.
   Turn away from the skid while pumping your breaks.

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.

1. Dump a bucket of water on it.
   Cover it with a lid.
2. Smother it with baking soda.
   Use a fire extinguisher.

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.

1. Alpha
   The letter "E"
2. Omega
   Time

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."

1. Ozone
   Acremonium
2. Mucor
   Petrichor

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.
