[EX Q]: I believe Robert Kagan's "The War for America" series continues this tradition with volume 1, detailing both the origin and historical context of U.S. history since WWII.
[EX A]: Good Review

[EX Q]: This product is completely useless. It has no power at all and doesn't clean well at all. Even if it worked for my room I wouldn't use it. I wish I'd returned it. I'll go with a different brand next time. If you want to get the best one, you'll need one that actually works better. That way, it's worth buying in the end.
[EX A]:
Bad review
