Question

which type of sentence is this? in beijing, china, eight luxury residential towers that were designed by steven holl architects are connected on the twelfth through eighteenth floors by enclosed glass and steel bridges. simple compound complex compound-complex

Explanation:

To determine the sentence type, we analyze its structure:

• A simple sentence has one independent clause. But this sentence has a dependent clause ("that were designed by Steven Holl Architects") modifying the noun "towers", along with the independent clause ("eight luxury residential towers... are connected...").
• A compound sentence has at least two independent clauses joined by a conjunction, which is not the case here.
• A complex sentence has one independent clause and at least one dependent clause. Here, the independent clause is "eight luxury residential towers... are connected on the twelfth through eighteenth floors by enclosed glass and steel bridges", and the dependent clause is "that were designed by Steven Holl Architects" (a relative clause acting as an adjective to modify "towers").
• A compound - complex sentence has at least two independent clauses and at least one dependent clause, which is not applicable here as there's only one independent clause.

So the sentence is complex.

Answer:

complex
