Hydrogeology is a science dealing with the properties, distribution, and circulation of water on the surface of the land, in the soil and underlying rocks, and in the atmosphere. The hydrologic cycle, a major topic in this science, is the complete cycle of phenomena through which water passes, beginning as atmospheric water vapor, passing into liquid and solid form as precipitation, thence along and into the ground surface, and finally again returning to the form of atmospheric water vapor by means of evaporation and transpiration.
The term "geohydrology" is sometimes erroneously used as a synonym for "hydrogeology." Geohydrology is concerned with underground water. There are many formations that contain water but are not part of the hydrologic cycle because of geologic changes that have isolated them underground. These systems. are properly termed geohydrologic but not hydrogeologic. Only when a system possesses natural or artificial boundaries that associate the water within it with the hydrologic cycle may the entire system properly be termed hydrogeologic.

(B) Water depositing minerals on the banks of a gorge through which the water runs
(C) The trapping of water in a sealed underground rock cavern through the action of an earthquake
(D) The water becoming unfit to drink through the release of pollutants into it from a manufacturing plant
(E) The changing course of a river channel as the action of the water wears away the rocks past which the river flows

Solution 1:
In first paragraph, the author is telling what the hydrology is, and what are the phases of hydrology.
In the starting of the second paragraph, the authoring is using a word “erroneously”, which implies that there is some myth or misconception. In the next lines author is telling the difference between hydrology and geohydrology any why they can't be used as synonyms.
We can say that author is correcting a misconception
- • Answer 1: Option C
Solution 2:
In the second paragraph, author is telling what falls in the category of geohydrology.
- • Geohydrology contains the study of water which is isolated underground.
Option B: Water depositing mineral on the bank of George are not related to water isolated underground. Incorrect.
Option C: Water is trapped underground due to earthquake --- water is isolated underground, Correct.
Option D: Talking about condition of water. Incorrect
Option E: Water in river --- Water is not isolated underground. Incorrect
Answer 2: Option C
Solution 3:
“Many formations” is used in second paragraph and it is used to differentiate between hydrology and geohydrology.
The option which is in line with our inference is Option A. which is talking about clarifying a distinction.
Answer 3: Option A

4 minutes .. all correct
1. The author's primary purpose is most probably to
(A) present a hypothesis
(B) refute an argument
(C) correct a misconception = in the first paragraph, author defines hydro geology and hydrologic cycle.. in the second paragraph, introduces a confusion between Geohydrology and hydro geology and later in the paragraph clears the misconception
(D) predict an occurrence
(E) describe an enigma
2. It can be inferred that which of the following is most likely to be the subject of study by a geohydrologist?
(A) Soft, porous rock being worn away by a waterfall - out of scope
(B) Water depositing minerals on the banks of a gorge through which the water runs - out of scope
(C) The trapping of water in a sealed underground rock cavern through the action of an earthquake = as per second paragraph, Geohydrology deals with water formations which is underground specifically. Hence this option is correct. Only option choice that deals with underground water
(D) The water becoming unfit to drink through the release of pollutants into it from a manufacturing plant - out of scope
(E) The changing course of a river channel as the action of the water wears away the rocks past which the river flows - talks about river and rocks, not underground
3. The author refers to "many formations" primarily in order to
(A) clarify a distinction - highlights the distinctions between hydrologic cycle formation components and underground water formations which are not a part of hydrologic cycle
(B) introduce a subject
(C) draw an analogy
(D) emphasize a similarity
(E) resolve a conflict
