Answer :
The sentence that has a grammatical error is: "Our panel of industry experts are evaluating the system's efficiency this month."
Here's why:
1. The subject "panel" is singular, so the verb should also be singular. In this case, the verb "are" is plural, which does not match with the singular subject "panel." The correct form should be: "Our panel of industry experts is evaluating the system's efficiency this month."
Therefore, the sentence "I'm confident that her team's speed and accuracy will improve with time" is correct in terms of grammar and spelling.
