Solution: d)

The fullerenes are a large class of allotropes of carbon and are made of balls, ‘cages’ or tubes of carbon atoms.

Nanotubes are nano-structures made of fullerenes with properties including high tensile strength, high electrical conductivity, high ductility, high heat conductivity, and relative chemical inactivity.

Nanotubes can be used to reinforce graphite in tennis rackets because they are very strong. Due to the above-mentioned properties, they are also used as semiconductors in electrical circuits.

The nanotube’s structure allows it to be used as a container for transporting a drug in the body. A molecule of the drug can be placed inside the nanotube cage. This keeps the drug ‘wrapped up’ until it reaches the site where it is needed. In this way, a dose that might be damaging to other parts of the body can be delivered safely to, for example, a tumour.

Solution: c)

Solution: a)

Under Article 1 of the Constitution, the territory of India comprises three categories of territories: (a) territories of the states; (b) union territories; and (c) territories that may be acquired by the Government of India at any time. Every union territory is administered by the President acting through an administrator appointed by him.

An administrator of a union territory is an agent of the President and not head of state like a governor. The President can specify the designation of an administrator; it may be Lieutenant Governor or Chief Commissioner or Administrator.

Solution: b)

Real GDP, which is the GDP after taking away the effect of inflation, is a derived metric. All Budget calculations start with the nominal GDP.

Real GDP = Nominal GDP — Inflation Rate

However, from the perspective of the common people, real GDP is what matters. The difference between the real and nominal GDP shows the levels of inflation in the year.

• The Pradhan Mantri Awas Yojana Gramin (PMAY-G) was formerly called the Indira Awas Yojana and was renamed in March 2016. It is targeted at promoting accessibility and affordability of housing for all of rural India with the exceptions of Delhi and Chandigarh.

Solution: a)

Under it, CO2 gas is injected with residual oil in the ageing field in which total oil production has been declining.

It reduces its viscosity and makes it easier to displace oil from the rock pores. CO2 gas also swells oil, thereby pushing it towards the producing well for extraction.

CO2- Enhanced Oil Recovery (EOR) works most commonly by injecting CO2 into already developed oil fields where it mixes with and ‘releases’ the oil from the formation, thereby freeing it to move to production wells. CO2 that emerges with the oil is separated in above-ground facilities and re-injected into the formation.

CO2 EOR is an important component of U.S. oil production.

Statements 2 and 3 are incorrect.
