Correct Answer: C

Rationale: After Mother Jones's publication detailing the harsh conditions of child labor in cotton mills, it is likely that public awareness increased, leading to public outcry. This heightened awareness and outrage often result in legislative actions being taken. Therefore, it is reasonable to predict that laws were passed to prevent child labor, as the excerpt vividly describes the unsafe and exploitative working conditions faced by children. Choices A, B, and D are incorrect because the publication would not have encouraged more children to work in such harsh conditions, led to the closure of cotton factories, or increased the pay scale for child laborers; instead, it would have prompted societal action to protect children from such exploitation.

Correct Answer: D

Choice A talks about the increased odds of accidents but does not capture the essence of the passage.

Rationale: Raoul estimates that he will need to use the library computer for approximately an hour and a half. Since each 15-minute period beyond the initial 30 minutes incurs a $3 charge, for a total of three additional 15-minute periods, Raoul will need to pay $9 ($3 x 3 = $9). Therefore, Raoul can expect to pay $9 for his computer use at the library. Choices B, C, and D are incorrect as they do not align with the information provided in the extract.
