Answer is Right!
Answer is Wrong!
The correct answer is A. remain silent.
The other options are incorrect because they do not describe the situation accurately.
- Option B, remain serious, is incorrect because the class was not serious. They were laughing.
- Option C, remain mute, is incorrect because the class was not mute. They were laughing.
- Option D, remain disturbed, is incorrect because the class was not disturbed. They were laughing.
The class could not keep a straight face on hearing the strange pronunciation of the new teacher. This means that they were laughing. They were not silent, serious, mute, or disturbed.
