Question

Choose the option that best completes the sentence: 
"She was so tired ___________ she could hardly keep her eyes open.''

• A. but
• B. that
• C. although
• D. because

Hint:

Use ``so... that'' to link a cause with its result.

Answer 1

The Correct Option is B

To complete the sentence, we need to choose the conjunction that accurately connects the two clauses, reflecting cause and effect, or a reason for the action. The sentence given is: ''She was so tired ___________ she could hardly keep her eyes open.''

Let's evaluate the options:

• but: This conjunction is used to contrast ideas, which doesn't fit as we are not introducing a contrasting idea here.
• that: This conjunction introduces a result or outcome, which fits perfectly as it shows the effect of being tired.
• although: This introduces a contrast or exception, which doesn't align with the idea we are expressing.
• because: This explains a reason or cause, but it doesn't fit the construction of "so...that" which implies a consequence.

Therefore, the correct option to complete the sentence is that. The sentence becomes: ''She was so tired that she could hardly keep her eyes open.''
