Hi there.
00:03
In this question, we are looking for the disaster that would have a prolonged effect.
00:12
And they define prolonged here for you, mentioning that it's characterized by a large spread over time.
00:41
Okay, so let's look at our options here.
00:43
First option, letter a, is a terrorist attack with a dirty bomb.
00:50
All right, well, this is going to definitely cause immediate impact.
00:53
And it's also probably going to take some time to clean it up, but it's only going to affect its initial area.
01:02
Wherever it is initially causes impact is where you're going to have long -term radiation.
01:16
So it's not going to have a large spread over time.
01:20
It may take a little bit of time to clean up this specific area where the bomb was dropped, but it's not going to spread from that location.
01:28
All right, let's look at letter b.
01:31
So letter a is not going to be our answer...
