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 provides essential information to identify the noun it modifies, without commas. A non - restrictive clause adds extra, non - essential info and is set off by commas.

• In "We took a kayak to a beach where sea turtles hatch", the clause "where sea turtles hatch" is restrictive as it tells us which beach (the one where sea turtles hatch), no commas.
• The other options have non - restrictive clauses (set off by commas) as the info in the clause is extra: "which I read in one day" (about travel books), "which has so many penguins" (about Antarctica), "who travels extensively" (about the Dalai Lama).

Answer:

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