find the relative clause. if it is nonrestrictive, set it off with commas. if it is restrictive, submit the text without making any changes. during his tour of the organic chocolate factory, samuel learned about the theobroma cacao which is a cacao tree native to the rain forests of central america.

Explanation:

A relative clause is a clause that modifies a noun or noun phrase. In the sentence "During his tour of the organic chocolate factory, Samuel learned about the Theobroma cacao which is a cacao tree native to the rain forests of Central America", "which is a cacao tree native to the rain forests of Central America" is a non - restrictive relative clause. Non - restrictive relative clauses provide additional information about the noun and are set off by commas. To remove the relative clause, we can just take out the part within the commas.

Answer:

During his tour of the organic chocolate factory, Samuel learned about the Theobroma cacao.
