Question

trade unions differed from labor unions in that trade unions were organized by immigrants. skilled workers. employers. unskilled workers.

Explanation:

To solve this, we recall the historical context of trade unions and labor unions. Trade unions in history were typically organized by skilled workers, focusing on specific trades (crafts) requiring specialized skills. Labor unions, in contrast, often included unskilled workers. Immigrants weren't the defining group for trade unions, and employers wouldn't organize unions for workers (as unions advocate for workers against employers). So the correct option is the one about skilled workers.

Answer:

B. skilled workers. (assuming the second option is labeled B; if the original options had no labels but the second box is "skilled workers", then "The second option (skilled workers)" )
