      People on a college campus were more likely to give money to the March of Dimes if they were
asked for a donation by a disabled woman in a wheelchair than if asked by a nondisabled woman. In
another   1   , subway riders in New York saw a man carrying a stick stumble(绊脚) and fall to the floor.
Sometimes the victim had a large red birthmark on his   2  ; sometimes he did not. In this situation, the
victim was more likely to     3     aid if his face was spotless than if he had an unattractive birthmark. In
    4   these and other research findings, two themes are   5   : we are more willing to help people we
like for some reason and people we think  6  assistance.
     In some situations, those who are physically attractive are more likely to receive aid.   7    , in a field
study researchers placed a completed application to graduate school in a telephone box at the airport.
The application was ready to be    8   , but had apparently been "lost". The photo attached to the
application was sometimes that of a very    9    person and sometimes that of a less attractive person.
The measure of helping was whether the individual who found the envelope actually mailed it or not.
Results showed that people were more likely to   10   the application if the person in the photo was
physically attractive.
      The degree of     11  between the potential helper and the person in need is also important. For
example, people are more likely to help a stranger who is from the same country rather than a foreigner.
In one study, shoppers on a busy street in Scotland were more likely to help a person wearing a(n)  
   12     T-shirt than a person wearing a T-shirt printed with offensive words.
      Whether a person receives help depends in part on the "worth" of the case. For example, shoppers
in a supermarket were more likely to give someone.   13   to buy milk rather than to buy cookies,
probably because milk is thought more essential for   14   than cookies. Passengers on a New York
subway were more likely to help a man who fell to the ground if he appeared to be    15   rather than
drunk.
