Answer:
Examining the rosebushes, Earl discovered many beetles.
Step-by-step explanation:
A misplaced modifier is a word or more complex structure (phrase or a clause) that modifies the wrong word in a sentence giving it grammatically correct, but completely illogical meaning. So this sentence is telling us that Earl discovered many beetles that were examining the rosebushes. It is obvious that beetles can not examine and that this phrase (examining the rosebushes) is modifying the wrong word ( beetles instead of Earl).
We also have to pay attention to punctuation which changes when we place modifier on the right place, comma should separate modifier and the rest of the sentence.
