Taking great care (A) while believed(B) the block of ice, the artist chiseling (C) that this would be his greatest sculpture (D) yet.

In the question below, four words are highlighted, which may not be correctly placed. Choose the correct replacement in between the highlighted words that can give appropriate meaning to the sentence.

The correct answer is Only (B)-(C).

Let's analyze the given sentence and the placement of the highlighted words step-by-step:

Original Sentence:
"Taking great care (A) while believed (B) the block of ice, the artist chiseling (C) that this would be his greatest sculpture (D) yet."

Analysis of Words & Grammatical Structure:

1. Position (B): The phrase "while [verb] the block of ice" requires an action verb describing what the artist is doing to the block of ice. "Believed" does not make sense here. Instead, "chiseling" fits perfectly: "while chiseling the block of ice".

2. Position (C): The main clause needs a past-tense finite verb following the subject "the artist". The verb "believed" fits here naturally: "the artist believed that this would be his greatest sculpture yet."

Swapping (B) and (C):

If we swap word (B) believed with word (C) chiseling, the sentence becomes:

"Taking great care (A) while chiseling (B) the block of ice, the artist believed (C) that this would be his greatest sculpture (D) yet."

This sentence is grammatically correct and conveys a clear, logical meaning. Therefore, replacing/swapping (B)-(C) is the correct choice.
