MAIN IDEACHOICE AIS CORRECT

21. Question type: main ideaChoice ais correct. The first part of the paragraph explains how the rich were unaware of the plight ofthe poor and therefore did not care “ ‘one half of the world does not know how the other half lives.’That was true then. It did not know because it did not care.” But the paragraph goes on to say that itwas only when conditions became so bad did it become “no longer an easy thing” for the rich to ignorethem. Although choices b,c, and dmay be correct statements, they do not sum up the main idea ofthe whole paragraph.Choice jis correct. The meaning of this phrase can be found throughout the passage, but since thename of the passage is “How the Other Half Lives” and it is about the conditions of the poor, one canreasonably assume it refers to the poor.
