Question 45: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42. A study was set up to examine the old marriage advice about whether it’s more important to be happy or to be right. Couples therapists sometimes suggest that in an attempt to avoid constant arguments, spouses weigh up whether the point is worth the grief of marital discord. The researchers from the University of Auckland noticed that many of their patients were adding stress to their lives by insisting on being right, even when it worked against their well-being. The researchers then found a couple who were willing to record their quality of life on a scale of 1 to 10. They told the man, who wanted to be happy more than right, about the purpose of the study and asked him to agree with every opinion and request his wife had without complaint, even when he profoundly didn’t agree. The wife was not informed of the purpose of the study and just asked to record her quality of life. Things went rapidly downhill for the couple. The man’s quality-of-life scores fell, from 7 to 3, over the course of the experiment. The wife’s scores rose modestly, from 8 to 8.5, before she became hostile to the idea of ​​recording the scores. Rather than creating harmony, the husband’s agreeableness led to the wife becoming increasingly critical of what he did and said (in the husband’s opinion). After 12 days he broke down, and the study was called off because of severe adverse outcomes.” The researchers concluded, shockingly, that humans need to be right and acknowledged as right, at least some of the time, to be happy. They also noted this was further proof that if given too much power, humans tend to “assume the alpha position and, as with chimpanzees, they become very aggressive and dangerous.” It is often said that there can be no peace without justice, and that’s true of domestic sphere. Obviously the results are to be taken with extreme caution, since this was just one couple with who-knows-what underlying issues before. But the study’s chief author, Dr. Bruce Arroll, maintains that the question of happiness vs. rightness, theoretically, could be settled by scientific inquiry with a wider sample. “This would include a randomized controlled trial,” he says. “However, we would be reluctant to do the definitive study because of the concern about divorce.” In paragraph 1, the study was conducted in order to ________.
