Final answer:
The answers to the grammar exercise are 'does,' 'barks,' and 'respect.' The homophones are context-dependent, like 'hear' to detect sound and 'here' for location. The comma corrections depend on clauses in the sentences, demanding an understanding of the grammatical structure.
Step-by-step explanation:
Practice Exercise in English Grammar
It's clear we are dealing with English grammar, specifically verb conjugation and the correct usage of homophones. Let's address each question one by one.
Sentence Completion with Verbs
Sonam does his work on time. The correct answer is 'b)' because 'Sonam' is a singular noun, and with the third person singular in the present tense we use 'does'.
A dog barks at every sound. The proper choice is 'c)' 'barks,' which is the third person singular present tense form of 'to bark.'
We respect our elders. The correct answer is 'a)' 'respect' because 'we' is a first person plural subject, and thus the verb should be in the plural present tense without an 's' at the end.
Homophones
- The sound 'hear' is the correct homophone in 'Can you hear the phone ring from here?'
- 'Two' as in the number is correct in 'they sold it for two bucks a pop.'
- 'It's' is the contraction for 'it is' and should be used in ' It's hard to find'
- To meet someone refers to arranging a meeting, not the food 'meat.'
Comma Insertion and Omission
Correcting punctuation requires an understanding of complex sentences and independent clauses. For example, when we add a missing comma it will look like this: 'Construction continued unabated for more than two months, I wasn't getting much sleep.
