Lisa: Hi, Tim. So, are you doing some last-minute shopping before the weekend?

Tim: Well, actually, I'm looking for supplies to put together 72-hour kits for each member of my family.

Lisa: [A] 72-hour kit? What's that?

Tim: Basically, a 72-hour kit contains emergency supplies you would need to sustain yourself for three days in case of an emergency, like an earthquake.

Lisa: An earthquake?! We haven't had an earthquake in years.

Tim: Well, you never know; you have to be prepared. Hey, if earthquakes don't get you, it could be a flood, hurricane, snowstorm, power outage, fire, alien attack.

Lisa: Huh, the food might be nasty, but I guess you could survive ... barely.

Tim: Well, the food doesn't have to taste bad; just select things that are easy to prepare, and you might want to include some basic comfort foods like a couple of candy bars. Then, you have to decide on the type of shelter you might need.

Lisa: A hotel sounds nice.

Tim: Yeah, but that's really not an option. The reality is that you might have to evacuate to a...
