The basket containing ten apples was made of cane.
This sentence requires correction based on the principle of subject-verb agreement.
The main subject of the sentence is "The basket," which is a singular noun. The phrase "containing ten apples" is a participial phrase acting as an adjective, modifying "basket." It does not alter the number (singularity or plurality) of the main subject.
Since the subject "basket" is singular, the verb must also be singular. The original sentence used "were," which is a plural verb. It should be replaced with the singular past tense verb "was" to agree with the singular subject.
In English grammar, 'since' and 'for' are prepositions used to indicate time, particularly with perfect and perfect continuous tenses, but they have distinct uses:
For: Used to express a duration of time. It answers the question "How long?". For example, "for three hours," "for five years," "for two days."
Since: Used to indicate a starting point in time. It answers the question "From when?". For example, "since Monday," "since 2010," "since morning."
In the original sentence, "two days" refers to a duration, not a specific starting point. Therefore, 'for' is the correct preposition to use.

Which of the two officers do you think is more senior?
In English grammar, when choosing between a limited number of options, the interrogative pronoun "which" is typically used instead of "who." While "who" refers to a person, "which" specifically implies selection from a definite, restricted group. In the given sentence, the phrase "of the two officers" clearly indicates a choice from a specific, limited set of two individuals. Therefore, "which" is the appropriate pronoun to ask for a selection from these two options.
