Historian: During the Industrial Revolution, for the first time in history, the productivity of the economy grew at a faster rate than the population and thus dramatically improved living standards. An economist theorizes that this growth was made possible by the spread of values such as hard work and thrift. But successful explanations need to be based on facts, so no one should accept this explanation until historical evidence demonstrates that a change in values occurred prior to the Industrial Revolution.

Summarize Argument
The historian argues that the economist's explanation of the economic growth that occurred during the Industrial Revolution should not be accepted until historical evidence shows that a shift in values occurred before the revolution. This is because valid explanations must be grounded in factual evidence.

Identify Conclusion
The conclusion is the historian’s claim that the economist's explanation of the economic growth that occurred during the Industrial Revolution should not be accepted until historical evidence shows that a shift in values occurred before the revolution: “no one should accept this explanation until historical evidence demonstrates that a change in values occurred prior to the Industrial Revolution.”

A
during the Industrial Revolution the productivity of the economy grew at a faster rate than the population
This is the phenomenon which the economist seeks to explain. It is not the historian’s overall conclusion.
B
the fact that the productivity of the economy grew at a faster rate than the population during the Industrial Revolution led to a dramatic improvement in living standards
This is context. It tells us the effects of the rapid growth that occurred during the Industrial Revolution, but not about the historian’s overall conclusion.
C
no one should accept the economist’s explanation until historical evidence demonstrates that a change in values occurred prior to the Industrial Revolution
This rephrases the conclusion.
D
the improvement in living standards that occurred during the Industrial Revolution was not due to the spread of a change in values
The historian is not arguing that the economist’s explanation is incorrect; the historian is arguing that there is insufficient evidence to accept the economist’s explanation.
E
values such as hard work and thrift did not become widespread prior to the Industrial Revolution
The historian does not make this argument. The historian’s argument is that there is insufficient evidence as to whether these values became widespread prior to the Industrial Revolution.
