Based on the novel The Lekki Headmaster, what grammatical issue did Bepo raise about Beesway Group of School's name?

This question tests the student's understanding of a specific grammatical issue raised by Bepo in the novel.

Bepo, being an English teacher with a keen eye for language, noticed that the school's name contained a grammatical error. The name "Beesway Group of School" uses the singular "School" where the plural "Schools" is required. Since the institution comprises a group (i.e., more than one school), the correct form should be "Beesway Group of Schools." The preposition "of" followed by a countable noun referring to multiple entities demands the plural form.

The issue was not about the spelling of "Beesway," the absence of a hyphen, or the use of capital letters. It was specifically about number agreement: the word "School" should be "Schools" to reflect the fact that a group necessarily consists of more than one unit.

This is a common grammatical error in Nigerian English usage, where singular forms are sometimes used where plural forms are required after collective nouns.
