Question

choose the correct sentence:

• (red, triangle) they wasnt playing when the teacher ente- red.
• (yellow, circle) they werent play when the teacher entered.
• (blue, diamond) they didnt playing when the teacher ente- red.
• (green, square) they werent playing when the teacher en- tered.

Explanation:

1. Analizar la concordancia sujeto-verbo: "They" es plural, así que el verbo auxiliar negativo correcto es "weren't" (no "wasn't", que es singular).
2. Analizar la estructura del tiempo: La acción "play" está en progreso (o no) cuando la profesora entró, así que se usa el pasado continuo negativo: "weren't playing".
3. Analizar la forma gramatical: "They didn't playing" es incorrecto porque "didn't" requiere el infinitivo sin "to" ("play"), no la forma "-ing". "They weren't play" también es incorrecto porque "weren't" requiere la forma "-ing" para el pasado continuo. La opción verde tiene la estructura correcta: "weren't playing" (pasado continuo negativo) con el sujeto plural "They".

Answer:

Green option: They weren't playing when the teacher entered.
