dr. sanchez and her team have observed an unusual star in the andromeda galaxy. their data suggests that the star is being consumed by a nearby black hole. they write a scientific paper about their work and submit it to a scientific journal. other scientists read their paper and look for the unusual star as well.
the other scientists are participating in which of these activities?
a. data collection
b. peer review
c. developing a hypothesis
d. developing a theory

Explanation:

• Option A: Data collection is gathering new data, but here scientists are reviewing existing work, so A is wrong.
• Option B: Peer review is when scientists evaluate others' research (like the paper here) to check validity, which matches the scenario.
• Option C: Developing a hypothesis is proposing an explanation, not what's happening here.
• Option D: Developing a theory is a broader, well - supported explanation, not the case here.

Answer:

B. peer review
