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.
As the periodic bloodshed continues in the Middle East, the search for
an equitable solution must come to grips with the root cause of the
conflict. The conventional wisdom is that, even if both sides are at
fault, the Palestinians are irrational “terrorists” who have no point of
view worth listening to. Our position, however, is that the
Palestinians have a real grievance: their homeland for over a thousand
years was taken, without their consent and mostly by force, during the
creation of the state of Israel. And all subsequent crimes — on both
sides — inevitably follow from this original injustice.
