Combining Sentences

Hello,
Can anyone help check my answers to these examples?
The question is just:
Combine the following sentences to get only one independent clause.
(1) The campus parking problem is getting worse.
The university is not building any new garages.
Though the campus parking problem is getting worse, the university is not building any new garages.

(2) The US has been overly dependent on foreign oil for many years.
Alternate sources of energy are now only being sought.
While the US has been overly dependent on foreign oil, alternate sources of energy are only now being sought.

(3) Indiana used to be an agriculture state.
It has recently attracted more people.
Since Indiana is used to be an agriculture state, it has recently attracted more people.

(4) The room fell silent.

You've made a good start! My suggestions are in red.

(1) The campus parking problem is getting worse.
The university is not building any new garages.
Though the campus parking problem is getting worse, the university is still not building any new garages. This one is okay, though I recommend the additional wording. An alternative could be, 'The university is not building any new garages, so the campus parking problem is getting worse.'

(2) The US has been overly dependent on foreign oil for many years.
Alternate sources of energy are now only being sought.
While the US has been overly dependent on foreign oil, alternate sources of energy are only now being sought. Good! You left out the part about "for many years"...

(3) Indiana used to be an agriculture state.
It has recently attracted more people.
Since Indiana [STRIKE]is[/STRIKE] used to be an agriculture state, it has recently attracted more people.
Hard to sort out cause/effect with the given text. Maybe they are looking for 'Indiana used to be an agricultural state, but it has recently attracted more people.'

(4) The room fell silent.
The TV newscaster has reported the story of the earthquake.
We all stopped what we were doing.
Since the TV newscaster reported the story of the Earthquake, the room fell silent because we all stopped what we were doing. 'The room fell silent as the TV newscaster reported the story of the earthquake and we all stopped what we were doing.'
