Option D is the correct answer.
This is not mentioned as a reason in the passage. The focus is on staying informed, contributing to the field,
and publicizing their own work, not on expanding influence. Therefore, option D is the correct answer as it is the
only reason not mentioned in the passage.

Option A: The passage mentions that some academics review work to "keep abreast with developments in their
field," which aligns with the idea that reviewing helps them stay updated with cutting-edge ideas. This is a valid
reason.
Option B: The passage also mentions that some scientists post their reviews online "mainly to claim credit for
their work," which indicates that some view reviewing as an opportunity to publicize their contributions. This is
a valid reason
Option C: The passage states that some view reviewing as "a duty to the discipline," which is a form of service
to the academic community. Therefore, option C is also a valid reason.
