Answer the following question given this paragraph: Scientists find answers using tests : When scientists want to answer a question, they search for evidence using experiments. An experiment is a test to see if their explanation is right or wrong. Evidence is made up of the observations a scientist makes during an experiment. To study the cause of death in the chimpanzees, scientists may give the chimps nutrients in the form of nuts, berries, and vitamins to see if they are dying from a lack of food. This test is the experiment. If fewer chimps die, then the experiment shows that the chimps may have died from not having enough food. This is the evidence. Q: What is the term for a test to see if a scientific explanation is right or wrong? A:

OPTIONS:
- invention
- hypothesis
- generation
- experiment

Answer:
experiment
