“There’s” or “There are”?
I have this sentence in my thesis:
"There is likely to be rapid changes and new approaches to this problem in the near future."
I can't figure out whether that "is" is correct, or should be "are". It sounds wrong, because of the plural "changes", but it would sound correct in in "There is likely to be rapid change..." (no plural). Does that plural change change the verb conjugation?
What's the rule here, and why does this sentence sound weird?
