Question

which sentence contains a restrictive clause?
we took a kayak to a beach where sea turtles hatch.
the travel books, which i read in one day, were informative.
bird watchers often travel to antarctica, which has so many penguins.
the dalai lama, who travels extensively, recommends visiting new places.

Explanation:

A restrictive clause (also called a defining relative clause) provides essential information to identify the noun it modifies, and it is not set off by commas. A non - restrictive clause provides extra, non - essential information and is set off by commas.

• For the sentence "We took a kayak to a beach where sea turtles hatch", the clause "where sea turtles hatch" is a restrictive clause. It is used to define which beach we are talking about, and there are no commas around it.
• In "The travel books, which I read in one day, were informative", the clause "which I read in one day" is non - restrictive as it gives extra information about the travel books and is set off by commas.
• In "Bird watchers often travel to Antarctica, which has so many penguins", the clause "which has so many penguins" is non - restrictive, providing extra info about Antarctica and set off by commas.
• In "The Dalai Lama, who travels extensively, recommends visiting new places", the clause "who travels extensively" is non - restrictive, giving extra info about the Dalai Lama and set off by commas.

Answer:

A. We took a kayak to a beach where sea turtles hatch
