Aaron is working at his job as an editor of a science magazine when a reporter places an article on his desk entitled "Gene for Optimism Found."
To avoid confusing the readers about what the scientists most likely found, what could Aaron change the title to?
A) "Pessimists are Missing a Crucial Gene"
B) "Scientists Find Gene's Purpose is to Increase Optimism"
C) "Scientists Find the Single Gene for Optimism"
D) "Gene Found to be a Factor in Optimism
Answer: D
Rationale: While some traits are controlled by single genes, most complicated behaviors are controlled by multiple interacting genes. Furthermore, single genes often affect several traits. Claims that scientists have discovered the gene for a particular trait are usually overstating the fact that a gene has been found to be one of the factors affecting a trait, not the lone cause.
