Questions & Answers about El marcador cambia y muestra una esfera verde cuando el entrenador presiona el botón correcto.

What does marcador mean in this context?

In this sentence, marcador refers to a scoreboard or display (like a digital indicator) that shows information.

Why is cambia in the third-person singular present indicative?

Because the subject el marcador is singular (“the scoreboard”), and we describe a current or general action. Spanish uses the present indicative for actions happening now or habitually.

Why do cambia and muestra share the same subject without repeating el marcador?

In Spanish, you can coordinate two verbs with y (and) when they share the same subject. So El marcador cambia y muestra means “the scoreboard changes and shows.’

What’s the role of una before esfera verde?

Una is the feminine singular indefinite article (“a”). It agrees in gender (feminine) and number (singular) with esfera (sphere), which is a feminine noun.

Why is verde placed after esfera and not before?

Most descriptive adjectives in Spanish come after the noun. So esfera verde literally reads “sphere green,” which we translate as “green sphere.”
