4. Which statement combines these two simple sentences into one compound sentence? Sara wanted to ace her geometry test. She overslept. Sara wanted to ace her geometry test, but she overslept. Sara really wanted to ace her geometry test but overslept. Although Sara wanted to ace her geometry test,she overslept. Because she overslept, Sara wanted to ace her geometry test.

## Step 1<br />The problem asks us to combine two simple sentences into one compound sentence. A compound sentence is a sentence that contains at least two independent clauses. These clauses are connected by a coordinating conjunction (for, and, nor, but, or, yet, so) or a semicolon.<br /><br />## Step 2<br />Looking at the options, we need to identify which one correctly combines the two sentences using a coordinating conjunction.<br /><br />## Step 3<br />Option A: "Sara wanted to ace her geometry test, but she overslept." This sentence correctly combines the two sentences using the coordinating conjunction "but".<br /><br />## Step 4<br />Option B: "Sara really wanted to ace her geometry test but overslept." This sentence does not use a coordinating conjunction, so it is not a compound sentence.<br /><br />## Step 5<br />Option C: "Although Sara wanted to ace her geometry test, she overslept." This sentence uses a subordinating conjunction "although", which makes it a complex sentence, not a compound sentence.<br /><br />## Step 6<br />Option D: "Because she overslept, Sara wanted to ace her geometry test." This sentence also uses a subordinating conjunction "because", which makes it a complex sentence, not a compound sentence.
