A. We thought Beth’s investment was safer than any other investment.

B. We thought Beth’s investment was the safest than any investment.

C. We thought Beth’s investment was safer than any investment.

D. We thought Beth’s investment was the safest than any other investment.

Answer 1

Answer: The sentence that makes a logical comparison is A. We thought Beth’s investment was safer than any other investment.

Explanation: A logical comparison consists in establishing a difference and/or a similarity between two people, things or ideas. It usually includes a comparative adjective and a key word, such as "than". The sentence that makes a logical comparison is A. "We thought Beth’s investment was safer than any other investment" since, unlike B. and D., it includes a comparative adjective: "safer". Moreover, although C. also presents the adjective "safer" and the key word "than", the comparison established is not logical at all because the word "other" is missing. Without the word "other" the reader could not completely understand that Beth's investment is being compared with other investments. In that way, sentence A., which includes "safer", "than" and "other", is the correct option.

Answer 2

The sentence which makes a logical comparison is the following one:

A. We thought Beth’s investment was safer than any other investment.

Step-by-step explanation:

The sentence above is in comparative form (superiority). So is letter C, but it lacks the word "other", which in letter A makes it clear we are comparing an investment to another investment.

Letters B and D must be ruled out, since the verb is wrongly in superlative form (superiority): the safest than any investment/ the safest than any other investment.
