Directions : Read the passage given below and answer the questions by choosing the best/most appropriate options.
In the past 25 years, scientific studies have shown us what exactly friends are for : they slash our risk of mortality in half, double our chances of recovering from depression, make us 4.2 less likely to succumb to common cold. According to University of Oxford psychologist, Robin Dunbar, they're even responsible for our massive brains. Dunbar found that the biggest predictor of a primate's brain size is the magnitude of its social group.
Is there any evolutionary value in social attachment?
Recent neurological research suggests that's the case.
Naomi Eisenberger from the University of California wanted to know if there was any truth to the language, we use to describe social connection - that, for example, it makes us feel warm - hearted. For a 2013 study, she had half the participants hold a heat pack and the other half an unheated ball. Unsurprisingly, members of the former group registered more activity in regions that detect and reward physical warmth. She then collected messages from the participants' family and friends - half of these messages were loving while the other half were factual messages. When the subjects, who were monitored using brain scans, were read the tender messages for the first time, "the same neutral regions were active as with the heat packs". She says, "We know how important it is to have relationships, and we are borrowing from those brain regions that are associated with warmth to signal to us when we feel connected".
