Cooped up in a heated atmosphere, debarred the necessary exercise, remaining in one position for a series of hours, one set or system of muscles alone called into activity, it cannot be wondered at--that its effects are injurious to the physical growth of a child. where the bony system is still imperfect, the vertical position it is compelled to retain, influences its direction; the spinal column bends beneath the weight of the head, bulges out laterally, or is dragged forward by the weight of the parts composing the chest, the pelvis yields beneath the opposing pressure downwards, and the resistance given by the thigh-bones; its capacity is lessened, sometimes more and sometimes less; the legs curve, and the whole body loses height, in consequence of this general yielding and bending of its parts. background information: this is an excerpt from a british report about child labor in 1833. what conclusion does this passage support? a) factory work children become stronger. b) factory work prevented children from growing normally. c) factory work caused children’s bodies to mature at a younger age. d) factory work required too much work from children’s undeveloped muscles.
