Mrs. Ibidun Gloss expressed deep appreciation to Bepo for contributing what she called an "unrivalled quota"…

Step 1: Analyze the question The question asks for the meaning of the phrase "unrivalled quota" in context. Mrs. Ibidun Gloss is thanking Bepo for what he contributed to the growth of Stardom.

Step 2: Explain the vocabulary

• Unrivalled means having no equal; unmatched, unparalleled, incomparable.
• Quota means a share or portion that someone contributes or is entitled to. In ordinary usage, "to contribute one's quota" means to make one's own contribution or share of effort.

So "unrivalled quota" means a contribution or share that no one else matches.

Step 3: Test each option

• A. Bepo's incomparable and exceptional contribution to the growth of the school. "Incomparable" matches "unrivalled" and "contribution" matches "quota". It also fits the context of "growth of Stardom".
• B. His savings over the years. Quota does not mean savings, and nothing in the phrase points to money kept over time.
• C. Contribution to the development of the school's building. This is too specific. The phrase says "growth" in general, not buildings only.
• D. Buying a large chunk of the school's shares. This is also too narrow. Quota does not mean shares in the financial sense here.

Step 4: Answer Option A is the only one that captures both words accurately without adding details that the phrase does not support.

Exam tip: In vocabulary-in-context questions, break the phrase into its parts, define each word, then pick the option that gives the general meaning without adding extra detail. Options that are too specific, like C and D, are often traps.
