Grammar and literature: 

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.

None of us are perfect. = None of us is perfect.

The definite article "the" is required before "Oxford of the East" because it functions as a specific and unique title or epithet for Dhaka University.

In this context, "Oxford of the East" refers to a singular, well-defined entity or comparison, highlighting Dhaka University's reputation and academic standing in the region, analogous to how Oxford University is perceived in the West.
