Final answer:
The sentence in question is a compound-complex sentence with two independent clauses and one dependent clause.
Step-by-step explanation:
The sentence "She wanted to win the game, and everyone else wanted to win too, so it became very competitive" is a compound-complex sentence. This type of sentence contains two or more main clauses and at least one subordinate clause. In this case, the sentence has two independent clauses: 'She wanted to win the game' and 'everyone else wanted to win too', which are joined by the coordinating conjunction 'and'. The dependent clause 'so it became very competitive' starts with 'so', which is considered a coordinating conjunction when used to connect two clauses in this manner. Overall, the sentence has two independent clauses and one dependent clause.
