The exchange-rate effect is one of the reasons why the aggregate demand curve is downward sloping. a. True
b. False

True.

Explanation:

True, the given statement is right because the exchange rate or price of the currency is inversely related to the demand. when the exchange rate increases that means the price of the currency is increasing and in that case, the demand for the currency falls. If the exchange rate falls or the price of currency falls then demand for the currency rises that indicate the inverse relationship between the exchange rate and the aggregate demand. therefore, the aggregate demand curve is sloping downwards.

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
