A country operates under a flexible exchange rate system. When the central bank lowers the interest rate during a recession, investment spending will decrease, the exchange rate value of the currency will, and net exports will.

decrease; increase

Explanation:

This is the case because as the central bank of that country lowers interest rate, with the goal recovering from the recession, but because the interest rate is low, the value of the country's currency (exchange rate) will decrease as a result of low investment spending.

When this occurs there will be an increase in net exports as a result of foreign demand because the prices of the country's export is now lower.

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.
