Excellent job with Q2 and the determinants of elasticity.

The calculations in Q5 are all correct but the conclusion isn't, although in the individual comments Jonathan and Qunshan got it right and Natashia got half of it right. Please have a look at their answers:
Positive EY = normal good
Negative EY = inferior good
ED > 1 elastic
ED < 1 inelastic.

Cheers!
