Hi Jenny,

I find both answers offered as correct a little strange.

In this sentence: 1)When the news spread (how new goldfields were discovered ) in Nome, Alaska, thousands abandoned Dawson, the site of THE previous gold rush. I would say: ‘were being discovered’

and in this sentence: (2) (a)(DESPITE) its cultural importance, the Daily Gazette (b)(lost) 70 percent of its subscribers since 1920 and, by 1955, ©(was losing) (d)(as much as ) $200,00 a year. (e)( No error.) I would say: ‘has lost 70% since 1920’ ‘and by 1955 was losing …’
