Question

which sentence contains an underlined restrictive clause?
the books that are stacked neatly on the top shelf belong to my great - grandfather.
the girl who broke the downstairs window with a baseball is knocking on the front door.
the store allowed the items that were purchased less than thirty days ago to be returned.
the restaurant, which had its grand opening two months ago, is always crowded.

Explanation:

Las cláusulas restrictivas son esenciales para la identificación del antecedente en la oración y no se separan con comas. En estas opciones, las cláusulas subrayadas definen específicamente "los libros", "la chica" y "los artículos", siendo esenciales para la comprensión del significado de la oración. En cambio, "which had its grand opening two months ago" en la última opción es una cláusula no restrictiva, ya que está separada por comas y no es esencial para identificar "el restaurante".

Answer:

• The books that are stacked neatly on the top shelf belong to my great - grandfather.
• The girl who broke the downstairs window with a baseball is knocking on the front door.
• The store allowed the items that were purchased less than thirty days ago to be returned.
