Favorite Pet is a Fish

I died and came back to life. My blood is not easily able to go through my body. My favorite pet is a fish. Who am I?

A shark. Sharks experience tonic immobility, also known as apparent death, where they appear to have died. Blood does not easily flow through their bodies, forcing sharks to swim continuously to circulate their blood. Lastly, sharks have pet fish called Remora (sometimes called suckerfish). They feed on parasites on the sharks and leftovers, and they use the shark as transport and protection.A big thanks to Saravana for answering this.

How Can You Pass the Tree

A car is on a narrow road with a tree in the middle of it. How can the car pass the tree?

Show the answer »

The tree is in the middle of the road as measured by length, not in the middle of it by width. In other words, the tree is growing on the side of the road, but it is equidistant from either end of the road, and therefore in the middle.This makes it quite easy to pass the tree as you just drive on the road, unless you’re texting and you run into said tree. If this is the case, stop texting.Thanks to everyone’s input on this one!

An Elevator Accident

I’m in an elevator with two other people. When it reaches the first floor, one person gets out and six get in. When it reaches the second floor, three people get out and twelve get in. At the third floor, five leave and nine enter. It rises to the fourth floor, one person gets on and the doors close. Suddenly, the elevator cable snaps and the car smashes to the ground. No one survives the fall, yet I’m alive and know exactly how many people go on and off the elevator at every floor. How is this possible?

Show the answer »

I got off at the first floor. I’m a security guard and knew how many people got on and off the elevator by watching the surveillance footage.

Four Cards

Four cards are placed in front of you on the table, each with a number on one side and a color on the other. The visible cards show 3, 8, red and brown. Which cards should you turn over in order to test the truth of the statement that if a card shows an even number on one face, then its opposite face is red?

four-cards

Show the answer »

You’d need to turn over only the 8 and brown card. Only a card with an even number on one face and which is not red on the other face can invalidate the stated rule. If you turn over the 3 card and it’s not red, it doesn’t invalidate the rule, nor does turning over the red card and finding it has the label 3.This test was devised by Peter Cathcart Wason and is known as the Wason selection task. Less than 10% of test subjects got it correct in two separate studies.

The Long River

How many times does the letter S appear in the name of the longest river in the world?

Show the answer »

Zero. The Nile is the longest river in the world. Some claim the Amazon as the longest, but that too has no “S”es (that looks weird but I don’t know how else to write the plural of “s”). The Mississippi is the 4th largest river in the world according to a href=”https://en.wikipedia.org/wiki/List_of_rivers_by_length”>Wikipedia.
