Answer:
Providing answers for a writing course is less clearcut than for other language areas. In some exercises
there is only one possible answer, but in other cases
several possibilities exist. Teachers need to use
common sense, and accept any reasonable answer. In
the case of exercises where students can choose their
own topic and it is therefore impossible to provide an
answer, students still appreciate having an example
answer, and so some have been included.
Explanation:
The context of the bold words in each sentence have been analyzed thus:
1. Approved
2. Showy
3. Spontaneous
4. Stop
5. Stop and prevent
In the first sentence, the boldened word, Sanction was used in a positive sense since the teacher judged the thesis to be a good idea. So to sanction in this context means to approve.
In the second sentence, ostentatious means showy since the showman wore flashy jewelry.
In the third sentence, the word impromptu means spontaneous since the drama was not planned.
In the fourth sentence, the desist means 'to stop'.
In the fifth sentence, the word preclude means stop and prevent. The teacher was encouraging the student not to let his bad grades stop or prevent him from reaching his goals.
