Statement I: "The teacher asked the students to quietly read the passage and answered the questions afterward." The correct form should be "and answer the questions afterward." The verb should be in the base form "answer" after "and." Statement II: "The seminar on climate change will be held in the auditorium on Tuesday." This statement is grammatically correct. Statement III: "Despite of the heavy rain, the marathon runners continued the race." The correct form should be "Despite the heavy rain." The use of "of" after "Despite" is incorrect.
