Professor Aminova has observed that most of her students, when writing essays, tend to begin their conclusion with the phrase “Therefore.” She believes that this habit was not acquired from her own teaching but rather from her colleague, Professor Karimov, who in his second-year classes strongly emphasizes that students should always begin their conclusions with “Therefore.” Professors Aminova and Karimov are the only instructors who teach the required writing courses in the first and second year.
Which of the following, if true, would most strengthen Professor Aminova’s conclusion?
(A) When teaching at a previous university, Professor Aminova did not notice this habit among her students.
(B) Professor Aminova’s first-year students rarely begin their conclusions with “Therefore,” but her second-year students, who have all taken Professor Karimov’s class, use it frequently.
(C) Professor Karimov discourages students from beginning conclusions with “Thus” or “Hence,” urging them instead to use “Therefore.”
(D) Some students may have picked up the habit of beginning conclusions with “Therefore” from their high school teachers.
(E) Second-year students are generally required to write more essays than first-year students.
