1. Consider whether the following contracts have been frustrated:

1. Donna agreed to buy the Douglas Brew Pub from Kaitlin. Prior to signing the agreement, Donna was worried that her application for a liquor licence may be refused. Nevertheless, she decided to take the risk. Two months later, the British Columbia Liquor Licensing Authority refused to issue her a license because of her previous criminal convictions.

1. Amber is the lead singer in the country western band, Dougie Dogs. Her band has topped the charts during the past year due largely to her unique singing style. Before her concert in Vancouver, she loses her voice to laryngitis due to the inclement weather and is unable to perform.

1. Jed lands a lucrative contract to construct a waste disposal site next to a bog that has long been considered as unsuitable for building. Recognizing the bog's unique role in the ecosystem and the rare flora and fauna that inhabit the area, the provincial government passes legislation that converts the entire area into a protected ecological zone.
