2). 'B' The plural of ability is abilities.
3). 'A' The plural of crutch is crutches.
1. The correct plural form of radish is (C.) radishes.
The plural form of the word 'radish' is 'radishes' because the rule says that when a word ends in "-sh", "-es" must be added after "-sh" to make it plural. The same happens with words ending in "-ch" and "-x".
2. The word that requires dropping the end and adding -ies to make it plural is (B.) ability.
The final "y" in "ability" must be dropped and "-ies" must be added instead. This responds to the rule that states that in those words that end in a consonant + "y", the "y" has to be changed to "-ies" to make it plural. It is the case of "ability", which ends in the consonant "t" + "y".
3. The sentence that contains a plural spelling error is (A.) She had to use crutchs for several weeks after breaking her leg.
In this case, the word that contains a plural spelling error is "crutchs". The correct plural form of this word is "crutches" since when a word ends in "-ch", "-es" must be added at the end.
