Ayuda con el diálogo "shopping"

Saludos.

Algunas prendas están en singular (cap, T-shirt, jumper, jacket) y otras en plural (shoes, socks, trousers, jeans...) Es importante que el alumnado use el verbo, determinantes y pronombres correctos para cada prenda.

Reproduzco aquí dos diálogos. Uno con un ejemplo en singular (jumper) y otro en plural (trousers). 

Estos diálogos se proporcionan como ejemplos. La mera repetición de los ejemplos en la prueba conlleva una calificación negativa.

[Jumper, singular]

"Can I help you?"

"Yes. Have you got this jumper in blue?"

"No, I'm sorry. But we got it in green."

"How much is it?"

"€24.99"

"OK. Can I try it on?"

"Of course. What size are you?"

"Medium."

"Here you are. The changing rooms are over there."

...

"It's perfect. I'll take it."

"That's €24.99, please."
