Parts of the following sentence have been given as options. Select the option that contains an error.
While I was walking to the store, my friend calls me and ask for a favour.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. my friend calls me and ask.
Error concept: Tense consistency and subject-verb agreement
What is wrong: The verbs 'calls' and 'ask' are in present tense, which is inconsistent with the past tense “was walking.”
Grammatical concept: In a sentence, all actions must match in tense when they happen at the same time.
Incorrectness of the concept in context: 'While I was walking' is in past continuous, so the verbs in the second clause should also be in past tense: 'called me and asked.'
How to correct: Replace 'calls me and ask' with 'called me and asked'
Correction: my friend called me and asked
Final sentence: While I was walking to the store, my friend called me and asked for a favour.
