The correct answer is:
B. In the story it is grim, but in the article it is positive.
The passage describes the Industrial Revolution in a predominantly positive light, highlighting advancements and benefits for society overall, while also acknowledging the challenges faced by the working class. In contrast, if the story (not provided here) portrays the Industrial Revolution in a grim manner, it would emphasize the hardships and negative aspects of this period, particularly for the working class.
