Imo. D.
Premise: Generally, marine biologists enter their field with the goal of doing important new research. They expect their colleagues to have similar goals.
Conclusion: Therefore, when any marine biologist becomes a household name in the field of documentary nature films,
most other scientists conclude that this biologist should no longer be regarded as a true colleague.It's required to identify assumption made by most other scientists, who concluded that marine biologist are no longer be considered a true colleague once he becomes prominent in the area of documentary nature films. Hence, it's required to identify the assumption by creating falsification Scenario that will invalid the conclusion when assumption is negated.
Falsification Scenario: Such marine biologist regarded as true colleague, even though he becomes a household name in the field of documentary nature films.
Potential assumption: What if such marine biologist continues to do important research even after becoming well known in his field of work.
Such assumption will support the falsification scenario and crumble the conclusion of the paragraph.
The explanation offered above for the low esteem in which marine biologists who make documentary films are held by research scientists assumes that
A. Serious scientific research is
not a solitary activity, but relies on active cooperation among a group of colleagues - It does not impact the conclusion even after negating the statement.
B. Research scientists tend
not to regard as colleagues those scientists whose renown they envy - nothing mentioned about enviousness in the argument. Hence, incorrect
C. A scientist can become famous as a marine biologist who makes documentary films without having completed any important research - Out of scope.
D. Research scientists believe that those who are well known as marine biologists who make documentary films are
not motivated to do important new research - Certainly, it will destroy the conclusion made by other scientists that renowned biologist is no longer to be considered true colleague. Hold it.
E. No important new research can be accessible to or accurately assessed by those who are not themselves scientists - Out of scope.
