A farmer planted the same variety of corn in two different fields, one in a field he had used before and one in a field that was new. The corn in the new field grew larger kernels than the corn in the old field. The farmer concluded that he should eat the corn from the new field and save the corn from the old field for see. Was this conclusion a good one? Why or why not?

a. No. Although anyone can form good conclusions based on data, the corn form the new field will grow larger kernels when it is planted next year.

b. No. The farmer is not a scientist and should not form conclusions. Also the corn from the new field will grow larger kernels when it is planted next year.

c. Yes. Anyone can form good conclusions based on data and the corn from the old field can grow large kernels as well as the corn from the new field.

d. No. The farmer is not a scientist and should not form conclusions even though the corn from the old field can grow large kernels as well as the corn from the new field.

Pat’s mom is an excellent cook. People keep telling Pat that she will also be a great cook one day because she will “get it from her mom”.

Based upon what you know about genetics, is this statement a fact or an inference? Write a short paragraph explaining your choice

Possible Answer:

This statement is an inference. Cooking is an acquired trait, not an inherited one. The fact that Pat’s mom is a great cook does not necessarily mean that Pat will also acquire this trait.
