Should it be:
a. What my wife brought were apples and oranges.
b. What my wife brought was apples and oranges.
NOT A TEACHER
(1) One expert gives these examples as a correct use of "what":
What to watch for is such things as dry, sandy layers.
What Jane is clutching to her bosom is four kittens.
What they saw was the white sand cliffs.
What these gentlemen need is some new moral values.
(2) Thus, if we accept that expert's examples, then
your sentence should read:
What my wife bought was apples and oranges.
(3) That expert also agrees with the moderator's advice:
If you do not feel comfortable saying/writing the correct
sentence, you can always express the idea in another way.
(4) 100% credit for this information goes to Mr. Wilson Follett
writing in his Modern American Usage (it is on page 233 of my
copy of the 1980 edition).
ok. So, how about this:
What bother/bothers geologists the most about depleting ozone layer is/are the risks that ice caps will melt, water will grow warm to sustain marine life, and that weather changes may result.
Please let me know the choice between bother/bothers and is/are.
We cannot change 'risks' to 'risk', because all the three mentioned are the risks. Please advice.
bhaisahab's sentence is fine - there is a risk of these things happening.
