The sentence is about 'neural prostheses' and has to do with nerves and transmitting signals with the end result being 'deaf being able to hear' or something similar to that. The word 'bones' do not fit in. Option (iii) is not coherent with the part of the sentence after the blank. The primary function of a nerve is to transmit signals from sensory receptors and clearly, the action of seeing comes under its ambit. Hence, option ii is the correct answer. 

By using tiny probes as neural prostheses, scientists may be able to restore nerve and make the blind see or the deaf hear.

‘Intellect’ is the ability with which a person understands. So, it will be best fitted with ‘clever’ as it denotes the one who is intelligent and quick to notice things. ‘Distinction’ needs to be sharp i.e. one that is easy to see or understand. So, ‘clear’ fits the second blank. ‘Poll’ is conducted to gauge i.e. to make a judgement about something, usually people’s feelings. 
Ans. B. 
Solution: The first blank needs a noun and refers to someone who have a scalp wholly or partially lacking hair. Thus, ‘bald’ fits best. The second blank needs a word which means a distinct period or stage in a process of change or forming part of something’s development. So, ‘phase’ fits best. In the third blank, ‘pour’ fits best as it means to flow rapidly in a steady stream.

Chink means a narrow opening, typically one that admits light. 'Chink in the armor' as a phrase means an area of vulnerability.

Duel means a prearranged contest with deadly weapons between two people in order to settle a point of honour.

Nemesis means a long-standing rival; an arch-enemy.

Here, the second blank mandatorily requires being filled with 'chink' to complete the phrase 'chink in the armor'. The first blank is connecting to 'sizing someone', which

means to carefully analyse the strength and weaknesses of a person, here 'duel' would make no sense.

This means option D is the correct response.

The sentence clearly means that the government is planning to establish or build family welfare centres for slums in cities.

'to set up' means to start something such as a business, organization, or institution. 

Another and centres do not go well grammatically, hence option A can be eliminated. 

Set for, set with and set in do not bring out the desired meaning, hence can be eliminated. 

Hence, up is the correct answer. 

You request for an asylum and not demand or charge for it. Thus, options A and C can be eliminated. 'Asylum petition' is a grammatically incorrect phrase. The correct term would be 'petition for asylum'. So, option B is the most appropriate answer.

Option I: The given sentences talk about the buildings. So the mention of killings of numerous people does not imply the same meaning as expressed in the statement sentences

Option II: It can be aptly placed before the first sentence that is given. 

Option III: The statement, ‘Syrian officials vowed to show no quarter…. eastern Ghouta’ can’t be deciphered from the sentences. The sentences are about buildings, not about the motive of Syrian officials. 
Therefore, option B is the apt answer. 

New statement: 
There are streets in Ghouta whose buildings are still standing relatively unscathed. They were spared during the bombardment because their inhabitants said – by mobile phone — they wanted to stay in their homes and would not resist the Syrian army.

One can clearly decipher that the first sentence is the wh-question while the second sentence is the answer to the question. 
Option I: If used, then the sentence will be grammatically incorrect. 
Option II: Because of ‘the reasons …another reason,’ it can be used. 
Option III: Unemployment, wages, and foreign goods are all parts of economics. So, it can be used. 
Therefore, option C is the apt answer. 
New statements: 
There are several reasons why 4.1% unemployment does not send wages and prices soaring and the reasons include falling union density and a flood of cheap foreign goods, but another reason is that real unemployment is much higher than 4.1%. 
Basic economics tells why 4.1% unemployment does not send wages and prices soaring and the reasons include falling union density and a flood of cheap foreign goods, but another reason is that real unemployment is much higher than 4.1%.

Statement II only fits with the first sentence and does not help in connecting the sentences. If statement III was used as the first part, the connector ‘because’ will make the sentence absurd. 
‘The acceptable number continue to rise’ can be deciphered from ‘“acceptable” target increases from 1.5 degrees Centigrade to 2 to 3 to 4 to 5 degrees Centigrade.’ Therefore, option A is the apt answer. 
 

New statement: 

The acceptable number continues to rise in order to keep business and pollution as usual churning as the “acceptable “target increases from 1.5 degrees Centigrade to 2 to 3 to 4 to 5 degrees Centigrade.

Alternative (I) doesn’t go with the statement because the option speaks of ruling out a fact or rule but the statement is giving a historical fact. 

Alternative (II) is incorrect because it is neither suitable to be used at the beginning or the middle of the sentence.
Alternative (III) goes with the statement as it uses the past tense and the given sentence is also in the past tense. Also, the given statements talk about a monument and so

does alternative (iii). Hence, (iii) is the only correct choice.

New sentence:

As he built the memorial in brick, mortar and marble, the monarch used the bewitchingly beautiful edifice to spread God's messages as he wanted the visitors to understand the meaning of those verses and reflect on them as they gazed at the beautiful monument on the banks of the Yamuna.

All the options are ambiguous and are not in coherence with the given statements.

Therefore, option E is the apt answer.
