Q:

Which one of the following elements is used as a timekeeper in atomic clocks?

A) Potassium B) Caesium
C) Calcium D) Magnesium
 
Answer & Explanation Answer: B) Caesium

Explanation:

When exposed to certain frequencies of radiation, such as radio waves, the subatomic particles called electrons that orbit an atom's nucleus will "jump" back and forth between energy states. Clocks based on this jumping within atoms can therefore provide an extremely precise way to count seconds.It is no surprise then that the international standard for the length of one second is based on atoms. Since 1967, the official definition of a second is 9,192,631,770 cycles of the radiation that gets an atom of the element called caesium to vibrate between two energy states.

Q:

Choose the option that best captures the essence of the text.
Issue of money, in the form of banknotes and current accounts subject to cheque or payment at the customer's order. These claims on banks can act as money because they are negotiable and/or repayable on demand, and hence valued at par and effectively transferable by mere delivery in the case of banknotes, or by drawing a cheque that the payee may bank or cash. Banks act as both collection and paying agents for customers, participating in interbank clearing and settlement systems to collect, present, be presented with, and pay payment instruments. This enables banks to economize on reserves held for settlement of payments, since inward and outward payments offset each other. It also enables ____________.

A) The offsetting of payment flows between geographical areas, increasing the cost of settlement between them. B) The offsetting of payment flows between geographical areas, reducing the cost of settlement between them.
C) The offsetting of payment flows only in urban areas, reducing the cost of settlement between them. D) The offsetting of payment flows only in rural areas, increasing the cost of settlement between them.
 
Answer & Explanation Answer: B) The offsetting of payment flows between geographical areas, reducing the cost of settlement between them.

Explanation:

The passage is based on economic development of the bank. It says that the economic growth of the bank in terms of the money is based on the cost of settlement. If this cost is reduced amongst the countries then the flow of payment will be maintained or vice versa. It is nowhere mentioned in the passage about rural or urban areas so we will take a general context. Hence option B is the correct option.
