read the following passage.

imagine, he says, if last year's moscow heatwave which sent average temperatures 14f above normal, and contributed to this year's smaller harvest next hit chicago and the midwestern bread basket. the us harvest could slump by 40 per cent, sending prices "off the chart" and cause "the global economy to start to unravel". as the climate changes, such extremes are likely to be more common.
which of the following is an example of the author's inductive reasoning in the passage?
a. the author reasons that moscow's heatwave would not do any damage to russia's economy.
b. the author states that recent heatwaves in moscow and chicago show that extreme weather is more likely.
c. the author reasons the us does not need any because of its strong economy.
d. the author states that the us harvest is unimportant because of the food storage.
