C) (i), (ii) and (iv) D) (i), (ii), (iii) and (iv)
 
Answer & Explanation Answer: C) (i), (ii) and (iv)

Explanation:

A software developer called Satoshi Nakamoto proposed bitcoin, which was an electronic payment system based on mathematical proof. The idea was to produce a currency independent of any central authority, transferable electronically, more or less instantly, with very low transaction fees. Bitcoin’s most important characteristic, and the thing that makes it different to conventional money, is that it is decentralized. Bitcoin is created digitally, by a community of people that anyone canjoin. Bitcoins are ‘mined’, using computing power in a distributed network.This network also processes transactions made with the virtual currency, effectively making bitcoin its own payment network.The bitcoin protocol –the rules that make bitcoin work –say that only 21 million bitcoins can ever be created by miners. However, these coins can be divided into smaller parts (the smallest divisible amount is one hundred millionth of a bitcoin and is called a ‘Satoshi’, after the founder of bitcoin). Bitcoin stores details of every single transaction that ever happened in the network in a huge version of a general ledger, called the blockchain.

Q:

Read the following passage and complete the paragraph with the help of correct options given below.
Working overseas is always a challenge for any professional and if you are an Indian, always strive to give-your best as Indians have always been considered intelligent, hardworking, talented and spiritual.
Working overseas was something many Indians desired but few achieved until the information technology boom opened several white-collar job opportunities for them in global markets. However, securing employment abroad may be an achievement but retaining it is quite a challenge as a professional requires constant demonstration of professionalism and exact the standards of competence.

A) Indians have always excelled in a competitive working environment. B) This makes them more enjoyable company.
C) Indians have always tried to bring out their best in competitive working environment. D) Indians are hard-working, competitive and professional employees.
 
Answer & Explanation Answer: A) Indians have always excelled in a competitive working environment.

Explanation:

Choice A is correct as it matches with the flow after a statement praising the professionalism of Indians, it is only logical to mention their excellence of working in a competitive environment. It also keeps up with the tone and general subject of the passage. Option 2 is a bad choice as it talks about being in their company which is not relevant in the context of the paragraph and therefore is incorrect as it is beyond the general theme. Option 3 is overall correct but we as we have to choose the best option so we have to cancel out on 3. Option 4 is obviously a lengthy reproduction of the sentence preceding the blank. As for option 5, it is incorrect as the statement does not keep up with the flow of the paragraph. Neither does it logically follow the previous sentence nor is it related to the next sentence.
