method of reasoning and parallel reasoning question are sure in LSAT but rare in GMAT. from what I have read about CR questions on various prep companies websites, method of reasoning /parallel reasoning question represents less than 2% of question type on CR. so low chances that a test taker will encounter such questions . However if you are doing well then you can get such a question.
