a. considerably
b. arguably
c. indecisively
d. without question
e. stemly

Answer 1

Hint: Undoubtedly means without any doubt. She undoubtedly got the first position in class means that nobody even thought that anybody else would come first. Now we have to find the synonym for undoubtedly, that is, a word which means the same as undoubtedly.

Complete answer:
 Let us look at the given question. It is talking about the Watergate scandal being the worst scandal in the history of U.S. political history. The sentence talks about it being undoubtedly true. So they are sure of the fact that the Watergate scandal was the worst scandal.

The meaning of undoubtedly combined with the context of the sentence shows that option d is the correct option.

Option a is wrong because considerably means to an extent. But the sentence says that they are sure about the scandal being the worst scandal. Considerably leaves room for doubt.
Option b is incorrect because the synonym of arguably is possible. Using ‘possibly’ does not show surety in the given question.
Option c is not correct because indecisively means to not be firm or sure about something. An indecisive person is not sure about his decisions.
Option e is incorrect because stemly is a word that does not exist in the English language. Therefore, it is not applicable.

Note: A synonym may be a phrase as well. Just because “without question” is not one word, it does not mean it does not qualify as a synonym. As long as the meaning is suitable, it qualifies as a synonym.
