While researching a topic, a student has taken the following notes:
<ul> <li>Gut microbiome studies on identical twins have produced mixed findings.</li> <li>One study found that twins shared more bacterial species than unrelated controls.</li> <li>Another study found gut microbiomes diverged sharply with diet differences.</li> <li>A third study reported that environment outweighed genetics by middle age.</li> <li>All three used different sampling methods and ages.</li> </ul> The student wants to highlight that the apparent inconsistency reflects methodological differences. Which choice most effectively uses relevant information from the notes to accomplish this goal?Which choice most effectively makes the student's point?
- Acheck_circle
While one twin study found shared bacterial species, others found that diet and adult environment outweighed shared genetics—differences likely reflecting variation in sampling methods and ages.
- B
Gut microbiomes are influenced by diet.
- C
A third study reported environment outweighed genetics.
- D
All three studies measured twins' gut microbiomes.
Explanation
The goal is that inconsistency is methodological. Choice C juxtaposes the contrasting findings and attributes the difference to method/age variation. The others give one finding or background.
