Questions 21 to 25 are based on the following passage.
I had an experience some years ago which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to officiate at two funerals on successive days for two elderly women in my community. Both had died "full of years," as the Bible would say; both yielded to the normal wearing out of the body after a long and full life. Their homes happened to be near each other, so I paid condolence (吊唁) calls on the two families on the same afternoon.
