Question

the silk saree are made in benaras.they are popular all over the world.combine with 'which'​

Answer 1

Here is the correct answer along with explanation:

The silk sarees, which are made in Benaras, are popular all over the world.

Explanation

Combining sentences using 'which' is known as relative clause structure. Relative clause is a kind of dependent or subordinate clause that gives more information about a noun or subject in the same sentence. There are two types of relative clauses. First type is Defining Relative Clause and the other type is Non-Defining Relative Clause.  

Defining relative clause functions or identifies which person or thing you are talking about. If left out, the sentence would appear incomplete. However, Non-defining relative clause only describes and adds extra information about somebody or something.  If left out, the sentence would still make sense. A non-defining relative clause is usually put in commas.

Answer 2

The silk sarees, which are made in Benaras, are popular all over the world.

Explanation:

Combining the given sentences by using Which will be as follows:

The silk sarees, which are made in Benaras, are popular all over the world.

In the above sentence, silk saree is the noun. We are stating it is popular all over the world. However, we are adding extra information about the noun as "it is made in Benaras." So it is known as relative clause structure. Relative clause is of two types, defining and non-defining. In both cases, the clause is used to provide extra information on the noun. But if the clause is removed and the sentence still makes sense, it is called Non-Defining Relative Clause. If the clause is removed and the sentence appears incomplete, it is known as defining relative clause. In the above case, it is non-defining relative clause.
