Student or Learner
I would be grateful for advice on the following sentence:
'It is not known how many escape attempts were made, but only a small percentage were successful.'
A friend tells me that the word after 'percentage' should be 'was', but I think that 'were' is correct because 'escape attempts' is plural. I live in the UK so the rules here may be slightly different than the US, but to substitute 'was' for 'were' in this sentence seems really odd to me.
I am not a teacher.
Welcome to the forum, Pedantric.
You're right and your friend is wrong.
'It is not known how many escape attempts were made, but only a small percentage [of them] were successful.'
'It is not known how much money was stolen, but only a small percentage [of it] was recovered.'
