Attempted by 104 students.
Show answer & explanation
Correct answer: A
Answer: extremely poor
Explanation: The conjunction 'but' introduces a contrast between the two parts of the sentence. The first part says his knowledge was excellent, so the second part must present an opposite idea about his classroom performance.
'extremely poor' fits because it provides a strong negative contrast to 'excellent', matching the meaning signaled by 'but'.
'good' is incorrect because it is positive and does not contrast with 'excellent'.
'desirable' is incorrect because it means appropriate or wanted, not poor performance, and therefore does not create the required contrast.
'praiseworthy' is incorrect because it is positive and means deserving praise, the opposite of a negative description.
Tip: Look for contrast words such as 'but', 'however', or 'yet' to determine whether you need an opposite or contrasting meaning in the blank.
