What is one reason why it it often hard to distinguish between offensive and defensive players?

In some sports there is no difference between offensive or defensive.

Explanation:

In games like tennis, even when it's double tennis so it's two people, the players are neither one nor the other. In sports without set roles such as football or rugby for example, it's not possible to constantly be only offensive or defensive.

But also, players can, depending on the sports, switch between offensive and defensive easily.

In football you get set players with set roles in where to play, especially because it's a team sport.

And a lot of the time the shirts aren't labelled with those two words on them either. So it's a very vague question. But I would mostly just say that in a lot is sports there is no difference.

is this a genuine question or is it on a quiz or something? lol

explanation:

this disease is :

* endemic (present in a defined area that is a village)

* a bacterial infection (treated with antibiotic)

* communicable by contact (by the hands)

manu-porterage is the most common mode of transmission, it transmits germs from one individual to another via the hands. this concerns infections of exogenous origin.

endemic disease, or endemic disease, refers to a disease that is constantly present in a given population, often tied to a specific geographic origin, as opposed to a pandemic that is not a sporadic disease.

antibiotics are molecules that have the property of killing (bactericidal) or limiting the spread (bacteriostatic) of bacteria.
