The study of these ________ about sound is called acoustics.
DSSSB - 2023,
Answer: B
The correct pair is 'unpleasant; questions'. The first blank is part of the list 'pleasant sounds and ____ sounds', so it needs the opposite of pleasant, and unpleasant fits. The second blank follows the series of questions in the passage (Where does sound come from? How does it get to your ears?), so 'questions about sound' fits and acoustics is the study of such questions.
'Horrid' is much stronger than needed, 'friendly' is not the opposite of pleasant for sounds, and 'repellent' is an odd choice. Also, 'demands', 'quizzes' and 'suspicions' do not fit questions about how sound works. Only the second option makes sense at both blanks.
