Writing Skill and Proofreading

Most smartest' is a double superlative error. 'Smartest' is already superlative.

Effect' is the noun form (the result); 'affect' is typically the verb form (to influence).

It's' (it is) requires an apostrophe. A semicolon is correctly used to join two independent clauses.

Intervening phrases like 'including the captain' do not affect the subject ('team'), which is singular.

Should have' (or should've) is the correct auxiliary verb form; 'of' is incorrect. 'Gone' is the correct past participle.

Who's' (Who is) is required to ask the question. 'Whose' denotes possession.

The correct spelling is 'Accommodate' (two c's, two m's).

The subject is 'variety' (singular), not 'dialects'. Therefore, 'is' is the correct verb.

Economics', like other names of fields of study ending in -s, takes a singular verb.

A number of' is plural. 'The number of' would be singular. Thus, 'have' is correct.

Bread and butter' functions as a singular unit representing a single meal, so it takes a singular verb.

The subject is 'quality' (singular), not 'apples'. 'Is' is the correct singular verb.

This corrects a dangling modifier; the original sentence implied the trees were walking.

Parallelism requires that a list of items share the same grammatical form (gerunds: reading, swimming, playing).

Parallelism requires the same verb tense in both parts of the 'not only... but also' construction ('did finish' and 'edited').

The sentence structure requires a main verb that matches the past tense established by 'worked' and 'studied'.

Parallel structure is maintained by using the gerund form for all three activities.

In 'neither/nor' constructions, the verb agrees with the subject closest to it. Since 'assistants' is plural, the verb must be 'were'.

Collective nouns like 'committee' take a singular verb when acting as a single unit.
