Question

Fill in the blank with the most appropriate option.
Some Tibetan nomads used yak butter as a ____________, one that often took the place of money in commercial transactions.
a) Promotion
b) Commodity
c) Formula
d) Refund
e) Register

Answer 1

Hint:We have to find a word that makes sense and gives meaning to the sentence. Here, the sentence refers to the yak butter as a ‘product’ or ‘item’. Therefore, try to find a word that completes the sentence in regard to this reference.

Complete answer:
Here, we can see that the yak butter is used as a product that is used as a food item and as money for commercial transactions also. This implies that it (the yak butter) is a commodity (product, item, good, etc). Therefore, the correct answer to the above question would be option (b), i.e. commodity.
This makes the sentence – ‘Some Tibetan m=nomads used yak butter as a commodity, one that often took place of money in commercial transactions.
Now, if we look at the other options we will see that they do not provide the required meaning to the sentence.
So, let us look into the options and see why they are incorrect -
Option (a) – Promotion: means to publicize a product, so if some nomads used yak butter as promotion and used it as money does not make sense.
Option (b) – is the correct answer as discussed above.
Option (c) – Formula: means a list of ingredients using which something can be made. This too does not provide the sentence with the required meaning.
Option (d) – Refund: means payback or repayment. If use it in the blank to complete the sentence there would be no meaning.
Option (e) – Register: means to record something, so if we say that some nomads used yak butter as a register, it does not make a proper sentence.
Therefore, the correct answer is option (b).

Note:
 The sentence talks about money and transactions. So do not get confused and try to use a money related option (like – refund, register, promotion) without understanding their meaning and what sentence they form when they are used to fill the blanks.
