Fill the correct degree of comparison:
Of all the solutions proposed, this one is by far the _______.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. most cost-effective.
Context: The sentence compares one solution with all the other proposed solutions, indicating the highest degree of effectiveness and economy.
Meaning of the words:
More cost-effective: Comparative degree; used for comparison between two things.
Most cost-effective: Superlative degree; used when comparing one with all others.
Cost-effectiver: Incorrect grammatical form.
Much cost-effective: Grammatically incorrect structure.
Correct word: Most cost-effective
Reason: The phrase “Of all the solutions proposed” indicates comparison among more than two items, so the superlative degree should be used. Therefore, “most cost-effective” is the correct choice.
Final Sentence: Of all the solutions proposed, this one is by far the most cost-effective.
Hence the chosen option is correct.
