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.

Q:

Which two atoms form an ionic bond?

Answer

Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another.. This bond generates two oppositely charged ions.


In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.


 


Example ::


One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.
