Elaine Hatfield and her co-workers randomly matched new University of Minnesota students for a Welcome Week dance. On the night of the blind date, the couples danced and talked for more than two hours and then took a brief intermission to rate their dates. What determined whether they liked each other?

a. similarity of values
b. similarity of academic competence
c. physical attractiveness
d. common family background

Option A,  similarity of values

Explanation:

People with same values preferably fall to like each other and hence they talk more as compared to people sharing other common bases such as family status, academic profile and attractiveness.  

It is very difficult to sustain a relationship if there is a difference in values.  

People sharing common thoughts on relationship’s importance tend to have a better understanding and coherent mutual relationship.  

Differences in values between two people in relationship tend to portray two different values for the same relationship which is difficult to carry on in long run.  

Thus, if values are same, a relationship could be long lasting and fruitful  

Hence, option A is correct

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
