If I understand correctly, they are words that are used to compare things.
Contrastive distribution occurs when two sounds placed in the same context produce different meanings. This is the case in the sounds [k] and [x] . For example: <em>[kano] 'do' versus [xano] 'lose'.
</em>
The same happens with the sounds [ç] and [c]. They are in constrastive distribution as in shown in the following example: <em>[çino] 'pour' versus [cino] 'move
</em>
In complementary distribution, where one sound occurs the other cannot. This is the case in the sounds [k] and [c] The first sound (palatal stop) appears before front vowels whereas the second sound (velar stop) appears elsewhere.
The sounds [ç] and [x] are also in complementary distribution. As in the previous example, the palatal appears before front vowels and the velar appears elsewhere
Answer:
A sudden hush fell on the crowd as Mr. Summers cleared his throat and looked at the list.
Explanation:
The phrase from the excerpt that best reveals how the social environment shifts as the lottery begins is "A sudden hush fell on the crowd as Mr. Summers cleared his throat and looked at the list.".
This is because, by mentioning that there was a sudden silence in the crowd as the lottery numbers were about to be called shows that the social environment shifted as the announcement was about to be made.
