Answer:
B. To help keep workers safe from unsanitary, corrupt, and dangerous working conditions.
Explanation:
Workers began to protest and denounce what they perceived as the unsanitary, corrupt and dangerous working conditions. That was the beginning of the labor movement.
Unions enhanced workers' ability to strike and demand concessions from the employers. Paid leave, social security, minimum wages, insurance (medical insurance in most European countries) ... those were some of the things the labor movement (boosted by unions) achieved around the world.
One reason could be that since England has colonized most of the countries in the past, the English language has been spread around. Another reason would be since English speaking countries like the US and Britain are powerful economically, knowing English is very important when making trades and business deals.
