Rain, snow, sleet, and hail are all forms of
a. humidity
b. evaporation
c. precipitation
d. condensation

C). Precipitation.

Explanation:

Precipitation takes place when the water vapor cools down and leads to condensation of water vapor and formation of tiny droplets that fall on the surface of the earth in several distinct forms.

It(precipitation) includes all the forms of water particles or moisture that descend from the atmosphere which could be either liquid or solid form. The liquid form would include falling of rain while the solid form would incorporate dropping of snow, sleet, and hail, etc. from the atmosphere. Thus, option C would be the correct answer.

the sentence does not violate the phrase structure second rule (introduced by noam chomsky) because noun phrases consist of a determiner such as a, the or every, and a noun. in the sentence, the noun phrase the cake includes a determiner (the) and a noun (cake).

on the other hand, the first rule indicates that a sentence encloses a noun phrase, followed by a verb phrase. the example sentence can be analysed as follows:

john (n) + ate (v) + the (det) + cake (n).
