A、A very overcrowded place. B、A tightly sealed container. C、A comfortable resort like a hotel. D、A place lacking water and food.

W: Hi, Tim. Are you doing some last-minute shopping before the weekend?
M: Actually, I’m looking for supplies to put together 72-hour kits for my family.
W: What’s that?
M: Basically, a 72-hour kit contains emergency supplies you would need to sustain yourself for three days in case of an emergency.
W: So, what do you keep in it?
M: Well, you should have enough food and water to last you three days, and you might want to pack a basic water filter in case your only water source turns out to be a pool of bug-infested water.
W: Ugh!
M: As for food, you should keep it simple: food that requires little or even no preparation and that doesn’t spoil.
W: That makes sense.
M: Then, you have to decide on the type of shelter you might need. You might have to evacuate to a shelter, possibly with hundreds or thousands of other people.
W: That doesn’t sound very fun... everyone packed together like sardines in a can.
M: I always pack a sleeping bag or small, lightweight tent in the event that I have to survive on the street or in a park.
W: Wow. What about money? I have a credit card.
M: That will help. But you’d better be prepared with coins and cash, and having small bills is a must.
W: So, what do you do to communicate with other family members in case you get separated?
M: I always pack two-way radios to communicate with the group. You can never depend on cell phones. Plus, you should decide on a meeting point in case your family gets separated.
W: Well, that sounds like a detailed plan.
