Some help with adjectives?

Question

ok I need some suggestion for like adjectives to add to these sentences. Basically the person who makes the best sentences by adding adjectives to these three will get 10 points

1)At the end of the hall were stairs that led to a room.

2)The car has a stereo and an air conditioner.

3)Theresa's interest in Science began when she attended the class.

Answer 1

Are these sentences standing alone?  If so you these sentences will work.  If they are part of a story, you'll need adjectives that make sense within the context.  

Anyway here goes:

1) At the end of the dark, damp hallway were creaking stairs that led to a long-abandoned room.

2) The luxury car has a state of the art stereo with crystal clear high definition sound, and air conditioner which reminds the owner of a cool summer breeze.

3) Theresa's insatiable interest in Science began when she attended Marine biology her freshman year.

Answer 2

10 points! Imagine that...

Tipsy Theresa's obsessive interest in paranormal Science began when she attended the crazy class

Answer 3

an adjective modifies a noun.

a noun is a person, place or thing.  A proper noun is the name of a specific person, or thing, for example, John J. Smith, or the White House.

..the long, dark, and dreary hall.......
