Question

consider the following research topic:
what determines right- versus left-handedness
which newspaper article would likely include the most relevant information about this topic?
\left-handed presidents: the eight lefties who led the united states\
\its all in the brain: why some people are left-handed\
\bias against left-handed people goes back thousands of years\

Explanation:

The research topic focuses on what causes right- versus left-handedness. The first article is about left-handed US presidents, which does not address the determinants of handedness. The third article covers historical bias against left-handed people, which is unrelated to the causes. Only the second article's title directly references explaining why some people are left-handed, aligning with the research topic.

Answer:

"It's All in the Brain: Why Some People Are Left-Handed"
