Answer:
The sentence is a Complex sentence
Step-by-step explanation:
First, we need to correct the grammar in the sentence. When all grammatical errors are removed, and it is properly punctuated, the sentence should read:
However, the result of all this labor is that the goddess of Pompeii is coming alive again through replanting.
A complex sentence ought to comprise of
a dependent clause AND an independent clause.
The dependent clause should start with a subordinating conjunction sometimes it could be a relative pronoun.
When the sentence is split at the punctuation we have:
Dependent Clause = However,
The word 'however' can also serve as an independent marker word. But in this case, it doesn't connote any meaning by itself
Independent Clause = the result of all this labor is that the goddess of Pompeii is coming alive again through replanting.
It's easy to see that in the Independent clause above, the goddess of Pompeii is the pronoun.
