Question

Seldom ............... such a complicated problem.

• A. I encountered
• B. Have I encountered
• C. When I encountered
• D. Have I encountered

Hint:

When"Seldom" starts a sentence, it causes inversion of the verb and subject.

Answer 1

The Correct Option is D

The given sentence is: "Seldom ............... such a complicated problem." To fill in the blank, we need to choose the option that correctly completes the sentence. The word "seldom" is an adverb of frequency and is typically used in formal contexts with an inversion. The absence of "such a complicated problem" after "seldom" indicates that we're dealing with a sentence structure involving auxiliary verbs. Therefore, the sentence is likely to be inverted.

In typical inverted sentences, when an adverb such as "seldom," "never," "rarely," etc., begins a sentence, the auxiliary verb comes before the subject. The correct structure here would be: "Seldom have I encountered such a complicated problem."

The correct choice is "Have I encountered," which is structured as:

• "Have" - auxiliary verb
• "I" - subject
• "encountered" - main verb (past participle)

Thus, the correct sentence is: "Seldom have I encountered such a complicated problem."
