The material used for sewing my dress is … to yours.

Analyze the question: The sentence is "The material used for sewing my dress is ___ to yours." We need the correct form of the adjective before the preposition "to".

Explain the concept: Words like superior, inferior, senior, junior, prior, preferable come from Latin comparatives (they end in -or). They already carry a comparative meaning, so:

• They are followed by to, not than.
• They cannot take more, most, or very (that would be a double comparison).

For example:

• ✔ "He is senior to me." ✘ "He is more senior than me."
• ✔ "This brand is superior to that one."

Step-by-step solution:

• A. most superior: wrong, since "superior" is already comparative and cannot take "most".
• B. superior: correct, as "superior to" is the standard structure.
• C. very superior: wrong, because "very" does not suit an adjective that already implies comparison, and it sounds unidiomatic here.
• D. more superior: wrong, because it is a double comparative.

The correct sentence: "The material used for sewing my dress is superior to yours."

Answer: B

Tip: Remember the "-or + to" group: superior, inferior, senior, junior, prior, anterior, posterior. If you see more/most/very in front of any of them, cross it out immediately. This is a favourite in WASSCE, JAMB and NECO.
