Assume that labor is the only factor of production and that wages in the United States equal $20 per hour while wages in Japan are $10 per hour. Production costs would be lower in the United States as compared to Japan if
U. S. labor productivity equaled 40 units per hour and Japan's 15 units per hour.

True

Explanation:

This simply means that the US would be at an advantage over Japan if in the U.S, labor productivity level of a worker equaled 40 units per hour while in Japan it is 15 units per hour.

Since a company overall performance is determine usually by wotkers production capacity, the US workers would be producing more in an hour for the company at reduced cost than Japanese workers.

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.
