Graduate Trainee Verbal Reasoning Dangote Cements Job

The verb 'prefer' must agree with the subject in number and person. Since the subject 'He' is singular, the verb takes the singular form 'prefers'.
The correct preposition used after 'prefer' is 'to' when comparing two things. Therefore, 'He prefers coffee to tea' follows correct subject-verb agreement and proper prepositional use.
Other options are incorrect because they either have wrong verb forms or incorrect prepositions.

The correct spelling is 'Separate', with an 'a' after the 'p'. Many people commonly misspell it as 'Seperate'.
The word 'Separate' functions both as a verb (to divide or keep apart) and as an adjective (distinct or different).
Other spellings are incorrect variations that do not exist in standard English usage.

The sentence expresses an action that will be completed before a specific time in the future ('by next year'). This requires the future perfect tense, formed by 'will have' + past participle.
Thus, 'By next year, she will have graduated' correctly indicates completion of an action before a future time reference.

'Ignorant' means lacking knowledge or awareness. Its opposite is 'Knowledgeable', which means well-informed and educated.
Other options like 'Uninformed' and 'Stupid' are close in meaning to 'Ignorant', while 'Simple' refers to being uncomplicated or modest, not the opposite of ignorance.

The subject 'guests' is plural, so it requires a plural auxiliary verb. The correct form is 'have' when used with plural nouns in the present perfect tense.
Therefore, 'The guests have already arrived' is grammatically correct. The auxiliary 'has' is singular, used with 'he', 'she', or 'it'.

'Optimistic' describes someone who expects the best possible outcome or has a positive outlook. Its opposite is 'Pessimistic', which refers to expecting the worst or focusing on negative outcomes.
Words like 'Cheerful', 'Hopeful', and 'Positive' are synonyms of 'Optimistic', not antonyms.

A comma is required after the interjection 'No' to separate it from the rest of the sentence. Hence, 'No, I can’t attend.' is correctly punctuated.
The other options are incorrect because they either omit the necessary comma or place it incorrectly within the sentence.

The idiom 'Once in a blue moon' refers to something that happens very rarely or infrequently. It originates from the rare occurrence of two full moons in one calendar month, which happens approximately every two to three years.
Therefore, it expresses an event that seldom occurs.

The sentence expresses a cause-and-effect relationship: she was tired, therefore she went to bed. The correct conjunction to show result is 'so'.
Hence, 'She was tired, so she went to bed' correctly connects the clauses logically and grammatically.

The adjective 'wide' is a one-syllable word, and its comparative form is made by adding '-er'. Thus, 'wider' is correct.
'Widest' is the superlative form used when comparing more than two items, while 'more wide' is grammatically incorrect.
