Answer Details

The correct word that best completes the sentence is "instigated." To "instigate" means to encourage or provoke someone to do something, usually something negative or harmful. In this sentence, the investigations revealed that the senior students encouraged or provoked the juniors to throw stones at the Principal's car. Therefore, "instigated" is the appropriate word to use here. The other options do not fit in the sentence context as well. "Infuriated" means to make someone extremely angry, which does not make sense in this sentence. "Integrated" means to combine or bring together, which is not relevant to the situation described in the sentence. "Instituted" means to establish or put into place, which is also not applicable in this context.
