Question

Add a prefix or suffix to make new words.
possible
appoint

Hint:

The phrase “instead of” always shows an alternative or substitution.
Adding clauses helps expand simple sentences into meaningful complex ones.
Prefixes like “im-,” “dis-,” “un-” often make words negative. Suffixes like “-ness,” “-ful,” “-tion” often change the form of the word.
When asked to make sentences, ensure they are grammatically correct and show the actual meaning of the word.

Answer 1

In part (a), prefixes and suffixes change the meaning of root words. Adding “im-” to “possible” makes it “impossible,” which means “not possible.” Adding “dis-” to “appoint” makes it “disappoint,” which means “to let down.”
In part (b), sentence construction is tested. The first example shows “possible” used to express feasibility, while the second shows “appoint” used in the sense of assigning responsibility.
