Question 1:
Most doctors dismiss male pattern baldness as a problem of heredity. A new theory, however, postulates that baldness can also result from number of external factors, such as a stressful urban lifestyle. Supporters of this new theory point out that baldness is twice as common among male who live in cities as it is among those who live elsewhere.
Which of the following most weakens the new theory described above?
A - Scientists have developed several drugs that halt baldness in men and can be taken internally
B - Census reports show that most men who are born in large cities live almost their entire lives within the city of their birth to remain close to their families
C - Most men do not develop male pattern baldness until they reach the age of 55, at which point their thoughts turn to pursuing a more restful lifestyle
D - Men who never lived in large cities are those who are least likely to develop male pattern baldness
E -A study determined that bald men are less likely to marry and reproduce

Question 1: (B)
Reason: First identify the conclusion: Baldness in males living in cities is caused due to stress. To weak the conclusion, we need to identify some other reason which actually tells the cause of baldness among the males of cities.
I understand that option (C) is attacking on conclusion, but is the attack is in right direction? No. The option (C) does not postulates any reason that support the premise that males living in cities faces the baldness problem twice to countryside (elsewhere) males. It just says that there could be another reason of baldness, which could be common among both the cities' males and also the countryside's males.
Whereas if we look at the option (B), it clearly states that the men who born in cities are remained at cities for their entire life. So if cities' males are not moving to countryside and countryside males may or may not moving to cities (in reality, yes countryside people are moving to cities in search of work), then there are high chances that defected gene that cause baldness among males will remain in the cities.
