Answer:
She believes that a thorough knowledge of your topic and plenty of practice is leading to success.
Explanation:
The first verb to believe is used in present simple tense because it refers to her habits or general truth. In this example, she expresses something in what is she certain. The second verb to lead is used in present continuous tense because this action will be also present in the future and refers to a permanent situation that will continue and does not stop in the present moment.
Answer:
It seems like the teacher is the one who is late.
Explanation:
Misplaced modifiers are the modifiers that are misplaced or placed in such a way that they are far from the noun they intend to modify. In other words, modifiers placed away from the intended noun and seem like they are modifying another word are known as misplaced modifiers.
In the given sentence, the modifier "that was late" was intended for Keiko's project. But rather, it is placed next to the noun "teacher" making it seem like it is the teacher who's late. This is a case of a misplaced modifier.
Thus, the correct answer is the third option.
