Read the following passage and answer the question. In an experiment on memory retention, two groups of students studied a list of words. Group A studied in a quiet room, while Group B studied in a room with background music. Immediately after studying, both groups recalled the same number of words. However, when tested again a week later, Group A recalled significantly more words than Group B. The researchers concluded that background music during study impairs long-term retention but not short-term recall. Which of the following, if true, would most weaken the researchers' conclusion?
- A.Group B students reported enjoying the music and felt more relaxed.
- B.Group A students had prior experience with memory tasks.
- C.The background music was played at a very low volume.
- D.Group B students studied for a shorter total time than Group A.
Kunci jawaban & pembahasan
Jawaban: Group B students studied for a shorter total time than Group A.
If Group B studied for less time, the difference in long-term retention could be due to study time, not music, weakening the conclusion.
