Mrs. Ibidun Gloss expressed deep appreciation to Bepo for contributing what she called an "unrivalled quota" to the growth of Stardom. What does "unrivalled...

To understand this phrase, consider each word separately. "Unrivalled" means without equal, unmatched, or incomparable. "Quota" in this context means contribution or share. Together, "unrivalled quota" means a contribution that is so outstanding that no one else's can match it.

Mrs Ibidun Gloss is expressing deep appreciation for Bepo's incomparable and exceptional contribution to the growth of the school (Stardom). She is saying that what Bepo contributed to building the school into what it has become is beyond what anyone else has done. The phrase captures both the magnitude and the uniqueness of his efforts.

The other options misinterpret the phrase:

• "Savings over the years" narrows the contribution to financial savings, but "quota" here refers broadly to contribution, not specifically to money saved.
• "Contribution to the development of the school's building" limits the meaning to physical infrastructure, whereas the phrase refers to the school's overall growth.
• "Buying a large chunk of the school's shares" introduces a commercial/investment idea that is not supported by the word "quota" in this context.
