Question: Read the following article and answer the question. Article: A predator kills and eats other animals as prey .Sometimes it also becomes food for other predators. Polar bears are the largest of all the land predators. They can run across snow and swim in icy water for hours without rest. Their favorite food is seal. Not all big animals live on small animals. Hippos have heavy bodies and huge mouths. But they don't eat animals. They just eat grass. Some predators use speed to catch their prey. Cheetahs are the fastest animals on land. They can run up to 70km an hour. Other predators use their senses to find their food. Sharks can see, smell, hear, feel and taste. They can also sense electrical currents( )from other animals' bodies. Some fish try to hide themselves, but with this sixth sense, sharks can always find them. Sharks have smooth bodies. This helps them swim without using lots of energy. They need to save their energy because they never really sleep and never stop hunting. Flying is a useful skill for many predators in the sky. The butcher bird is the most interesting predator. It has a special way of eating its prey. First it kills its prey. Then it hangs it on a fence or in a tree, just like a butcher hangs meat in his shop. Finally, it eats its prey. Some people hunt and kill more animals than any other predator. They not only hunt for food. They also hunt for fun. They kill sharks for their fins, and tigers for skins. Those human hunters are the worst predators on Earth. Question: Among the sharks, the tigers, the polar bears and some people, which are the most dangerous predators on earth? Answer:
OPTIONS:
- the sharks.
- the tigers.
- the polar bears.
- some people.

input with options: Read the following article and answer the question. Article: Almost everyone has dropped some food on the floor and still wanted to eat it.If someone saw you drop it, he or she might have shouted, " 5-second rule!" This so-called rule says food is OK to eat if you pick it up in five seconds or less.But is that true? Professor Anthony Hilton from Ashton University, UK, tested the rule with his students.They found that food dropped for five seconds is less likely to contain bacteria than if it sits there for longer. For the study, Hilton and his students tested a lot of foods----bread, pasta, cookies and candy--to see how much bacteria they had when they made contact with the floor.They allowed the food to lie on the different types of flooring--carpet , laminate and tile -- for three seconds to 30 seconds. Not surprisingly, the longer the food was on the floor, the more bacteria it had.And the type of floor where the dropped food landed had an effect.Bacteria are least likely to transfer from carpet, while they are most likely to transfer laminate or tiled surface after more than five seconds. The study also found that the wetter the food, the more likely it was to pick up bacteria.Although most people are happy to follow the 5-second rule, eating food dropped on the floor still carries an infection risk."It very much depends on which bacteria are on the floor at the time." Hilton told Forbes. Question: According to the article, the infection risk of the dropped does NOT depend on _ . Answer:
OPTIONS:
- how long the food sits on the floor
- what the dropped food is
- what the bacteria are
- what the weather is like that day
output: what the weather is like that day
