1. There may be genetic causes for the differences in how young the skin of identical twins looks.
Keywords: genetic causes, differences, young skin, identical twins
In the first paragraph, the writer argues that “Any differences between them (identical twins) – one twin having younger looking skin, for example – must be due to environmental factors such as less time spent in the sun.” So, there are no genetic causes for the differences in how young the skin of identical twins looks, only environmental factors.
=>ANSWER: FALSE
1. Twins are at greater risk of developing certain illnesses than non-twins.
Keywords: greater risk, illnesses
In terms of the risk of developing certain illnesses, the writer only compares identical twins with fraternal twins (at the end of paragraph 2), he does not make a comparison between twins and non-twins. So, the statement is not given.

1. Bouchard advertised in newspapers for twins who had been separated at birth.
Keywords: Bouchard, advertised, newspapers, separated
In this passage, the writer does not mention whether Bouchard advertised in newspapers for twins who had been separated at birth or not. In paragraph 4, we are only told that 137 sets of twins visited his laboratory. Therefore, the statement is not given.
