The part of the sentence that needs to be edited has to be chosen from the given sentences.
1. The correct line will be 'the moment. They are attending' (C)
Reason: The action in the sentence is in present continuous tense. Therefore 'are attending' will be the correct form of verb.
2. The correct line will be 'to check the engine problem of the machine on' (D)
Reason: The preposition used in the sentence is incorrect. The correct preposition will be 'on'.
3. The correct line will be 'Mr. Robert to call' (B)
Reason: The preposition 'to' is missing in the sentence. Without the addition of the preposition, the sentence becomes grammatically incorrect.
4. The correct line will be 'forward to having' (B)
Reason: In this sentence, the verb 'have' is functioning as a gerund. Therefore the '-ing' form of have has to be used here.
5. The correct line will be 'about the design process in' (D)
Reason: The correct preposition will be 'in'.
6. The correct line will be 'but we have never visited' (D)
Reason: The action of travelling and visiting has been done in the past, therefore the verb used here should be in past tense.
7. The correct line will be 'Stephen Curry has broken' (A)
Reason: The past participle form of the verb 'broke' should be used in the sentence.
8. The correct line will be 'he graduated' (D)
Reason: The sentence is speaking about the action done in the past, therefore the past form of the verb will be used.
9. The correct line will be 'My son has' (A)
Reason: Since the subject is in singular, therefore the auxiliary verb that needs to be used should also be in singular number.
10. The correct line will be 'eat noodles with' (C)
Reason: 'Did' is the helping verb used in the sentence and the main verb 'eaten' has been incorrectly used. The correct form of main verb will be 'eat'.
