I'll answer your question in the comments but what are the 2 sentences?
Answer:
He was upset because somebody stole his watch.
Explanation:
It makes sense to use stole instead of steal!
It also would be better to use "past tense"
Do I need to use your user name or do you want me to make up a name?
This sentence is complex because it contains both a dependant and an independent clause. Do not be fooled by the addition of "however" or the length of the sentence.
If you need reasoning, here you are:
Simple: has one independent clause
Compound: has two independent clauses (either joined by a coordinating conjunction or a semicolon)
Complex: contains a dependant and an independent clause
Compound-Complex: Contains at least two independent clauses and one dependent clause
Hope this helps! If you have any questions about what any of the words that I used in my explanation mean (such as an independent clause and a dependent clause), feel free to ask.
