7. how many points must a team win by to win a game?

a. 2
b. 3
c. 4
d. 5

c. 4

The number of points a team must win by to win a game depends on the specific sport or game in question. Different sports and games have different rules regarding the required winning margin.

In some sports, such as basketball, the winning team must have a score that is higher than the opposing team's score by a certain number of points, typically 2 points or more. So, option a. 2 points could be correct for some sports like basketball.

In other sports, such as tennis, badminton, and table tennis, players or teams must win by at least 2 points to secure a victory in a set or game. So, option a. 2 points could also be correct for these sports.

However, in certain sports like soccer (football) and field hockey, there is no specific requirement for the winning team to have a certain point difference. The winning team is simply the one that scores the most goals within the allotted time. So, options b, c, and d would not apply in these sports.

Therefore, the answer depends on the specific sport or game being referred to.
