Changes in real GDP reflect Question 12 options: a) both changes in prices and changes in the amounts being produced. b) neither changes in prices nor changes in the amounts being produced. c) only changes in the amounts being produced. d) only changes in prices.

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.

yup the answer is
