Underline TWO irrelevant sentences in the following paragraph.
The common view in social science of love relationship is not that opposite attracts but that like attracts like. In the animal world, however, this might not be true. People fall in love with others who share their interests and tastes and whose personalities are similar. Hill, Rubin and Peplau(1976)found only slight support for this view. On a great many characteristics, couples were not alike. On others ,couples were only somewhat alike . Couples did tend to be about the same age, to be equally good looking, to have similar IQ scores ,to be of the same religion, and to want the same number of children . But on each of these things, quite a few couples differ from one another. In fact, on only one question did most agree: on whether they were “in love". Consequently , love relationship varies from culture to culture.
