Final answer:
To indicate whether a statement is true or false, use a check mark for true and cross an x for false.
Step-by-step explanation:
A check mark is used to indicate a common basis for the name of a community, while an x is used to indicate that it is not a common basis. In this case, you would write a check mark for 'true' and cross an x for 'false'.
For example, if the question is 'Is the name of a community based on its location?', you would write a check mark if the answer is 'true', indicating that the name of a community is indeed based on its location. Conversely, you would cross an x if the answer is 'false', indicating that the name of a community is not based on its location.
So, to answer the question, you would write a check mark for 1) True and cross an x for 2) False.
