Answer:
Okay i may be wrong but
Step-by-step explanation:
The Spanish first settled in North America in the sixteenth century; they found that great numbers of Indians already inhabited the land.
Okay, so for this line this is how it's going to work:
1. The Spanish first settled in North America in the sixteenth century
That's independent
2. They found that great numbers of Indians already inhabited the land.
That's dependent because without the first sentence we don't know who "They" are.
3. The Spanish are the subject
4. Verbs are: Settled, found, inhabited
5. You're going to put a box around this ;
1. The Aztecs who lived in Mexico built Tenochitilan
That's independent
2. This city contained over 100,000 inhabitants and was built in the middle of a shallow lake.
That's dependent because without the first sentence we don't know which city they are talking about.
3. The Aztecs are the subject
4. the verbs are: Lived, built, contained
5. You're going to put a box around this ;
Hope this helps! I'm sorry if i'm wrong
