Answer #1

Answer:- (b) social intelligence hypothesis.

Explanation:- This hypothesis supports the results of Dunbar's test using data on brain anatomy. According to Dunbar, human intelligence is primarily means for surviving in large complex social groups and reproduce to increase their numbers not for solving the ecological problems. Primates need large brain size because their form of sociality is much more complex than other species. So the correct answer is option (b).

Background: Darwinism Today the theory of evolution is a well-supported, unifying principle in biology, which explains how life on earth began and developed. The scientific evidence overwhelmingly supports the idea that all living things share a common ancestry. Charles Darwin, a British naturalist, is the person most remembered for his contribution to how the process of evolution works. He wrote a book, published over 150 years ago, called On the Origin of Species, which was very controversial at the time....

Correctional services were interested in evaluating a cognitive-behavioural based intervention designed to reduce violence and offending. A group of researchers assigned nine offenders on parole into a control group for one year and recorded the number of violent incidents perpetrated by the offenders. Then, these offenders were given the intervention for one year and the number of violent incidents perpetrated by the offenders was recorded following the treatment. The researchers are interested in testing whether the treatment had any effect...
