Read the following passage and select the three inferences that are most firmly based on the given information. 1At the very bottom of the American social ladder are the homeless. 2They are people whose worldly goods fill a few shopping bags. 3Social workers usually find that these people once were better off, but that some misfortune led to their losing their home. 4An apartment building, for example, is sold to a developer, and its poor tenants are evicted. 5A breadwinner loses his or her job because of a plant closing or a long illness. 6A woman leaves an abusive husband but cannot afford an apartment of her own. 7Whatever the cause, the result is the same: a person, a couple, a mother and her children, or an entire family living on the street. 8Having fallen from a higher rung on the social ladder, many of the homeless are unable to regain their position.
