Identify the segment that contains a grammatical error. If there is no error, select 'No error.'
After I shut the door and started back to the living room, / he yelled something at me, / but I couldn't strictly hear him.

The correct answer is (c) but I couldn't strictly hear him.
Explanation:
The word "strictly" is incorrect in this context. "Strictly" means rigidly or exactly, and it does not fit here. The correct word should be "clearly" to indicate that the speaker could not hear what was said distinctly.
Corrected sentence:
After I shut the door and started back to the living room, he yelled something at me, but I couldn't clearly hear him.
Meanings of key words:
· Strictly: In a rigid or precise manner (incorrect here).
· Clearly: In a way that is easy to perceive, understand, or hear.
