Which three groups of sentences best use a variety of sentence patterns to convey meaning and the relationship between ideas? The delicious smell of cinnamon wafted from the kitchen. When I entered, I discovered my friend was making snickerdoodles. My friend was making cookies. My friend was in the kitchen. The cookies smelled delicious. In the kitchen, my friend was baking snickerdoodles. Their mouth-watering aroma drew me toward the oven. Attracted by a delicious smell, I approached the kitchen. My friend was baking snickerdoodles.

The three groups of sentences that best use a variety of sentence patterns to convey meaning and the relationship between ideas are:

1. The delicious smell of cinnamon wafted from the kitchen. When I entered, I discovered my friend was making snickerdoodles.

3. In the kitchen, my friend was baking snickerdoodles. Their mouth-watering aroma drew me toward the oven.

4. Attracted by a delicious smell, I approached the kitchen. My friend was baking snickerdoodles.

Explanation:

It is actually easier to start our analysis by the one group we eliminated:

2. My friend was making cookies. My friend was in the kitchen. The cookies smelled delicious.

Notice that in group 2, all we have are three independent clauses separated by a period. There is no complexity here - all we have are simple sentences. Besides that, there is also no complexity in the vocabulary being used. Only simple, common words are employed. Let's say this type of writing sounds a bit weak, even childish.

On the other hand, when we take a look at the other three groups, we notice the author was able to combine the sentences effectively with the help of pronouns, conjunctions, and modifiers. Not only that, but the author also uses more complex words - for example: "mouth-watering" instead of "delicious".
