The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
I have thought at / what you said / and I’ve decided / to take your advice.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. I have thought at
The error lies in the preposition 'at'. The verb 'thought' is not followed by 'at' in this context.
The correct phrase is: 'I have thought about' — we say 'think about something', not 'think at something.'
Corrected sentence:
I have thought about what you said, and I’ve decided to take your advice.
Why the other options are correct:
Option 1: and I’ve decided – grammatically correct.
Option 2: to take your advice – correct structure.
Option 4: what you said – grammatically correct as a noun clause.
