A.I. Explanation:

Correct answer: processes

Explanation: The word 'processes' fits grammatically as it is a plural noun that aligns with the context of bodily functions that involve water. It matches the structure of the sentence, which discusses various functions such as digestion and respiration, all of which are processes.

Meaning: 'Processes' refers to a series of actions or steps taken to achieve a particular end, in this case, the bodily functions that require water.

Wrong options:

• procedures: 'Procedures' implies a specific method or way of doing something, which does not encompass the broader range of bodily functions mentioned.
• methods: 'Methods' suggests a systematic way of doing something, but it is less inclusive than 'processes' in this context.
• developments: 'Developments' refers to the process of developing or being developed, which does not relate to the bodily functions that involve water.

Correct answer: remove

Explanation: The verb 'remove' is appropriate here as it indicates the action of taking away thirst, fitting grammatically and contextually with the sentence's focus on bodily needs.

Meaning: 'Remove' means to take something away or eliminate it, in this case, referring to quenching thirst.

Wrong options:

• confiscated: 'Confiscated' implies taking something away, usually by authority, which does not fit the context of satisfying thirst.
• eliminated: 'Eliminated' suggests completely getting rid of something, which is too strong for the context of quenching thirst.
• add: 'Add' implies increasing or including something, which contradicts the action of addressing thirst.

Correct answer: required

Explanation: The word 'required' fits grammatically as it indicates necessity, aligning with the context of water being essential for life. It is a strong adjective that conveys the importance of water for all living beings.

Meaning: 'Required' means something that is necessary or needed, emphasizing that water is crucial for survival.

Wrong options:

• compulsory: 'Compulsory' suggests something that is mandatory, which is too formal and does not match the tone of the sentence.
• essential: 'Essential' also means necessary, but 'required' is more commonly used in this context, making it a better fit.
• obligatory: 'Obligatory' implies a duty or requirement, which does not convey the same sense of necessity as 'required' in this context.

Correct answer: happen

Explanation: The verb 'happen' is suitable here as it indicates an occurrence or event, fitting grammatically and contextually with the inquiry about the consequences of water scarcity.

Meaning: 'Happen' means to occur or take place, referring to the potential outcomes of a lack of drinking water.

Wrong options:

• occurs: 'Occurs' is a synonym for 'happen' but is less commonly used in this interrogative context, making 'happen' a more natural choice.
• made: 'Made' implies creation or manufacture, which does not fit the context of discussing events or outcomes.
• come: 'Come' does not convey the same meaning of occurrence as 'happen' and is grammatically awkward in this context.

Correct answer: finished

Explanation: The word 'finished' fits grammatically as it indicates the state of being used up, aligning with the context of water availability. It is a past participle that describes the condition of drinking water.

Meaning: 'Finished' means to be completely used up or no longer available, referring to the depletion of drinking water.

Wrong options:

• refined: 'Refined' suggests a process of purification, which does not relate to the state of water being depleted.
• over: 'Over' does not convey a clear meaning in this context and is grammatically incorrect as it does not fit the structure of the sentence.
• come: 'Come' does not fit grammatically or contextually, as it does not describe the state of water availability.
