Directions: Read the sentence to find out whether there is any grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The corresponding letter of that part is the answer. If the given sentence is correct as it is, then choose option ‘No error’ as the answer response. (Ignore errors of punctuation, if any).

The Phoenicians manufactured (A)/ mainly glass vessels, (B)/ and this craft spread to (C)/ Mediterranean ports and Egypt. (D)

The correct answer is No error.

Explanation:
Let us analyze each part of the sentence for grammatical and idiomatic correctness:
- Part (A): "The Phoenicians manufactured" — The subject "The Phoenicians" is appropriately followed by the simple past tense verb "manufactured".
- Part (B): "mainly glass vessels," — The adverb "mainly" correctly modifies the noun phrase "glass vessels", serving as the direct object of the verb.
- Part (C): "and this craft spread to" — The coordinating conjunction "and" connects the two clauses seamlessly. The phrase "this craft" correctly refers to the trade or art of glass-making, and the phrasal verb "spread to" is used appropriately.
- Part (D): "Mediterranean ports and Egypt." — This phrase lists the destinations receiving the craft, correctly adhering to standard prepositional usage.

Since all parts of the sentence are grammatically and idiomatically sound, the sentence contains no errors.
