Credit two marks for justification/exemplification of each

For example:
- In our social practical investigation we could increase the
age range of our participants to include up to 65 years of
age (1) which would allow us to generalise our self-report
questionnaire results on obedience to a larger age range
(1).
- Our sample could include an equal number of males and
females from the college (1) which would give us a more
representative number of participant responses from both
genders to measure whether different genders perceive
men or women to be more obedient (1).
