Fill in the Blanks

As mentioned in the passaage ' 65 percentage of brain study...... makes it clear that option 4 is the correct answer.

Clearly mentioned in the second last  line which states by writing.

Spoken language for communication where he/she can interchange their view points thus option 4 is the correct answer.

Refer to the last statement it helps to interact and contact thus option 2.

The main reason/ function of language is to be able to communicate( it is through speech taht the mind i have is projected into other minds and those in turn become part of my own ) indicate communication.

The passage is talking about language thus the best answer is option 3.

In the passage it is clearly mentioned that  ' it was found that left hemisphere was larger and more highly developed than the right '. So option 1 is the correct answer.

It denotes an activity done before the teacher asks in the past.. So, past perfect will be used.

The sentence uses the future tense 'shall go', so the purpose clause should use the present tense 'can see' to indicate a future possibility.

The main clause is in the past tense ('could say'), so the subordinate clause must also be in the past tense to maintain sequence of tenses.

Other options do not fit the blank. Only 'is' correctly fits the blank.... "Virtue is its own reward."

The sentence describes a past action ('went to war') with a purpose. The past tense 'extended' is required to match the past tense of the main verb.

This is a third conditional sentence structure (If + past perfect, would have + past participle).

The reporting verb 'confessed' is in the past tense, so the action that happened before the confession must be in the past perfect tense.

The sentence is in the past tense ('appealed'), so the verb in the indirect question should reflect the past tense context. 'Need' is technically present, but in this specific construction, it functions as the required action.
