Text 1: Biologist Park argues that the human appendix is not a useless organ. Recent research suggests it serves as a reservoir of beneficial gut bacteria that can repopulate the intestine after illness, a function that may have been more important historically.
Text 2: Biologist Singh accepts that the appendix may have a minor role in gut microbiome reseeding but argues against overstating it. People with surgically removed appendixes show no measurable health disadvantage; whatever role the organ plays, it is one a healthy person can lose without consequence.
Both authors would most likely agree that
- A
humans cannot survive without an appendix.
- Bcheck_circle
the appendix may play some biological role.
- C
the appendix has no relationship to gut bacteria.
- D
the appendix is essential for survival.
Explanation
Both accept some biological role; they differ on its importance. A is shared. B, C, and D contradict at least one author.
