[EX Q]: I went to two stores trying to find the exact brand name products that Sandra Lee insist we use. Frustrated, I asked the store mananger who told me that the products I was looking for, Campbell's fat-free mushroom soup and Jello refrigerated vanilla pudding cups are no longer available in my area.Why make such a big fuss about using this or that brand when they aren't even available? I won't waste any more time travelling around town looking for the exact brand names needed to make the recipes in this book.I have better things to do! Maybe this book needs a "use-by " date before even more products become obsolete.
[EX A]: Negative

[EX Q]: Steve Milloy, author of this book, is a Washington, DC, lobbyist who has represented just about every polluting industry imaginable, especially the tobacco industry. If you doubt this, read the book Trust Us, We're Experts! by Rampton and Stauber, who have pages on Milloy, CATO, American Council on Science and Health, and their PR campaigns to smear health and environmental concerns as 'junk science' waged by evil public interest groups and activists like Ralph Nader. Pure industry propaganda.
[EX A]: Negative

[EX Q]: I enjoy your music so much and every last one of your songs touch my heart. As a teenager I consider you a positive appearance and influence to all the other young people that they can be used of God and that they can stay saved. Be Blessed and keep looking up because your help cometh from the Lord and if you acknowledge God in all you do he will direct your path and give you the desires of your heart. God Bless You, take care, and continue to let God use you!
[EX A]:
Positive
