Question 45: Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions: Climbing down the tree, one of the eggs was broken so he decided to throw it away.

climbing down => he climbed down

Wrong because when reducing the clause must have the same subject. But in both clauses “climbing down the tree” is an action that the subject “one of the eggs” cannot do, so the subject in the first clause cannot be “one of the eggs”.

When he climbed down from the tree, an egg broke so he decided to throw it away.
