The author’s assumption about scientific research is that
Answer & explanation
Answer: (c) it is never without some value
The author writes that “Scientific research is probably never completely valueless” — there is always a chance of some value. The assumption is that it is never without some value, not that it is always very valuable.
- ✗ (a) The author says the results may be of value to an investigator of talent; “never very valuable” is not what he assumes.
- ✗ (b) The passage does not grade research as sometimes very valuable; its claim is only about some value.
- ✓ (c) “Probably never completely valueless” means never without some value.
- ✗ (d) Too strong: the author admits research may seem “silly and insignificant” and claims only some value.
Remember · Match the strength of the passage’s claim: ‘never completely valueless’ is not ‘always very valuable’.
