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:

A passage with three blanks, followed by five options, each containing one word, is given. Choose the word that can fill all the three blanks.
The ability of humans to ___________ the landscape and recognize the consequences of doing so puts us in a peculiar position. There are several animals on earth that show this same kind of intelligence. Some animals have extensions to ___________ their environment and some do not. As a species we are assigned the duty to provide and proliferate. Our goal is to achieve stability for ourselves and our kin. However, we also have an obligation to maintain the environment, as we depend on the resources and services it provides. The question then becomes:
what is our role in nature? Do we have the right to _________ the land, factory farm animals, and pollute waterways? Or do we have an obligation to reduce our numbers and merely subsist? In order to answer these questions, we must rely on our knowledge of Earth, evolution, and our influence on the environment.

A) Aspects B) Pollutants
C) Employ D) Operate
 
Answer & Explanation Answer:

Explanation:

‘Aspects’ mean a particular part or feature of something. ‘Pollutants’ mean a substance that pollutes something, especially water or the atmosphere. ‘Employ’ means give work to (someone) and pay them for it. ‘Operate’ means (of a person) control the functioning of (a machine, process, or system). ‘Manipulate’ means control or influence (a person or situation) cleverly or unscrupulously. The passage hints towards unscrupulous usage of the environment for our own betterment. Thus, option E is the best fit answer for the given blanks.
