An inference draws conclusions based on evidence gathered through observation. The conclusion is reached logically on the basis of facts known to be true or assumed to be true. An inference can be seen as an interpretation of what is observed. An inference is an element of reasoning, an act of thinking.
Answer:
A. a year that was cool or dry
Explanation:
This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.
