Multiple choice

Which of the following is the correct spelling of 'pureifys'?

Directions: Read the following passage carefully and select the most suitable option according to the corresponding number in the passage.

The Hydrosphere is an imaginary (1) sphere. However, its importance is not imaginary. The hydrosphere contains all the water that is above, below, or upon the surface of the earth. It also includes (2) the water inside plants and animals. The larger part of the earth's hydrosphere is salt water. The water cycle pureifys (3) the atmosphere and surface water by removing (4) pollutants. It (5) supplies usable water to living things on land. It does so by purifying the saltwater of the oceans and by turning (6) it into fresh water. All life thus depends upon an "active hydrosphere." That means an intact or undamaged hydrosphere with a running (7) water cycle. Since all living things use water inside their bodies, an active hydrosphere and life travel hand in hand (8).

C Correct answer
Explanation

The misspelled word 'pureifys' should be corrected to 'purifies' - the third person singular form of the verb 'purify.' For verbs ending in consonant + y, change y to i and add -es. 'Purefies' and 'puriefies' don't follow this rule, and 'purifyies' incorrectly keeps the y.
