Question

In both Britain and the United States, what happened in the 1870s that limited child labor?

As unions became stronger, they didn’t allow children under 14 to work.
Laws passed in both countries prohibited children under 14 from working.
Laws passed in both countries limited children to work only 8 hours a day.
Compulsory education and attendance laws were passed in both countries.

Answer 1

Compulsory education and attendance laws were passed in both countries.

In Britain the 1870 Education Act began establishing elementary schools (leading to later compulsory attendance), and in the U.S. the 1870s saw many states adopt compulsory school laws — both developments reduced child labor by keeping children in school.
