Dear users of StackExchange
I came across this sentence which can be seen below:
"Finding quiet places have become very difficult in today’s noisy society."
I found the sentence on a website that helps students with English.
Upon further investigation, I learned that numerous people on the website stated the fact that the subject "Finding quiet places" is singular and therefore "have" must be corrected to "has".
At first glance, this sounds odd to me. Isn't the subject "Finding quiet places" plural? Furthermore, I couldn't get a well-explained answer to why "have" should be "has" instead. This is so confusing!
Can anyone help me with my question? Please do know that your help is greatly appreciated!
