Question

order the topics from broadest to narrowest. broader temperature drops in europe due to krakataus eruption the effect of krakataus eruption on global temperatures the 1883 eruption of the volcano krakatau narrower

Explanation:

Step1: Analyze the broadness of each topic

- "the 1883 eruption of the volcano Krakatau" is about the eruption event itself, a specific event.
- "the effect of Krakatau's eruption on global temperatures" is about the effect on a global scale, broader than a specific regional temperature drop.
- "temperature drops in Europe due to Krakatau's eruption" is about a specific region (Europe) and a specific effect (temperature drop), the narrowest.

Step2: Order from broadest to narrowest

First, the event of the eruption: "the 1883 eruption of the volcano Krakatau" is the base event. Then, the global effect: "the effect of Krakatau's eruption on global temperatures" is broader than a regional effect. Finally, the regional effect: "temperature drops in Europe due to Krakatau's eruption" is the narrowest.

Wait, no, correction: Wait, actually, the broadest should be the most general. Wait, "the 1883 eruption of the volcano Krakatau" is the event. Then, "the effect of Krakatau's eruption on global temperatures" is about the effect (broader than a specific region's temperature drop). Then, "temperature drops in Europe due to Krakatau's eruption" is the most specific (narrowest). Wait, no, maybe I got it reversed. Let's think again. The broadest topic is the one that covers the most general area, and the narrowest is the most specific.

- "the 1883 eruption of the volcano Krakatau" is about the eruption event (a specific event, but maybe the base). Then, "the effect of Krakatau's eruption on global temperatures" is about the effect on a global scale (broader than a regional effect). Then, "temperature drops in Europe due to Krakatau's eruption" is about a specific region (Europe) and a specific effect (temperature drop), so the narrowest. Wait, but actually, the order from broadest to narrowest should be: first, the eruption event (the 1883 eruption of Krakatau), then the global effect (effect on global temperatures), then the regional effect (temperature drops in Europe). Wait, no, maybe the other way. Wait, the "effect on global temperatures" is broader than "temperature drops in Europe" because global includes Europe. And the eruption event is the cause, so the broadest is the eruption event? No, maybe not. Let's re-express:

- "the 1883 eruption of the volcano Krakatau": this is about the eruption itself, a specific event.
- "the effect of Krakatau's eruption on global temperatures": this is about the effect of that eruption on a global scale (temperature), which is broader than a specific region's temperature drop.
- "temperature drops in Europe due to Krakatau's eruption": this is about a specific region (Europe) and a specific effect (temperature drop) from the eruption, so the narrowest.

Wait, but the question is to order from broadest to narrowest. So the broadest is the one that has the widest scope. So "the effect of Krakatau's eruption on global temperatures" is broader than "temperature drops in Europe" because global is wider than Europe. And "the 1883 eruption of the volcano Krakatau" is the event that caused the effects. Wait, maybe the correct order is:

1. the 1883 eruption of the volcano Krakatau (the event, which is the base, but maybe not the broadest). Wait, no, maybe I'm confused. Let's think of the scope:

- "the 1883 eruption of the volcano Krakatau": scope is the eruption event.
- "the effect of Krakatau's eruption on global temperatures": scope is the effect on global temperatures (broader than a single region's temperature).
- "temperature drops in Europe due to Krakatau's eruption": scope is temperature drops in Europe (narrowest, as it's a specific region and a specific effect).

Wait, but actually, the broadest should be the one that covers the most general topic. So the eruption event is a specific event, but the effect on global temperatures is about the impact, which is broader than a regional impact. Wait, no, maybe the correct order from broadest to narrowest is:

1. the 1883 eruption of the volcano Krakatau (the event, which is the cause, and the broadest in terms of the event itself)
2. the effect of Krakatau's eruption on global temperatures (the effect on a global scale, broader than a regional effect)
3. temperature drops in Europe due to Krakatau's eruption (the narrowest, specific region and specific effect)

Wait, no, that doesn't seem right. Let's take an example: if you have "animal", "mammal", "dog". The order from broadest to narrowest is animal, mammal, dog. So in this case, the "eruption event" is like "animal", the "global effect" is like "mammal", and the "regional effect" is like "dog"? No, maybe not. Alternatively, "the effect of Krakatau's eruption on global temperatures" is broader than "temperature drops in Europe" because global includes Europe. And "the 1883 eruption of the volcano Krakatau" is the event that led to the effects. So the broadest is the eruption event, then the global effect, then the regional effect. Wait, but maybe the other way: the global effect is broader than the eruption event? No, the eruption event is the cause, and the effect is a result. So the scope of the eruption event is the event itself, the global effect is the impact on a large scale, and the regional effect is the impact on a small scale. So the order from broadest to narrowest should be:

1. the 1883 eruption of the volcano Krakatau (broadest, as it's the event)
2. the effect of Krakatau's eruption on global temperatures (next, as it's the effect on a global scale)
3. temperature drops in Europe due to Krakatau's eruption (narrowest, effect on a specific region)

Wait, but I think I made a mistake. Let's re-express:

- "the 1883 eruption of the volcano Krakatau": this is about the eruption (a specific event, but the base).
- "the effect of Krakatau's eruption on global temperatures": this is about the effect of that eruption on global temperatures (broader than a single region's temperature drop).
- "temperature drops in Europe due to Krakatau's eruption": this is about a specific region (Europe) and a specific effect (temperature drop) from the eruption, so the narrowest.

So the correct order from broadest to narrowest is:

1. the 1883 eruption of the volcano Krakatau
2. the effect of Krakatau's eruption on global temperatures
3. temperature drops in Europe due to Krakatau's eruption

Wait, no, that can't be. Because the "effect on global temperatures" is a result of the eruption, so the eruption is the cause. But the scope of "effect on global temperatures" is broader than "temperature drops in Europe" because global includes Europe. So the broadest is the eruption event, then the global effect, then the regional effect.

Yes, that makes sense. So the order from broader to narrower is:

1. the 1883 eruption of the volcano Krakatau (broadest, the event itself)
2. the effect of Krakatau's eruption on global temperatures (next, effect on a global scale)
3. temperature drops in Europe due to Krakatau's eruption (narrowest, effect on a specific region)

Answer:

broader: the 1883 eruption of the volcano Krakatau
middle: the effect of Krakatau's eruption on global temperatures
narrower: temperature drops in Europe due to Krakatau's eruption

(When ordering from broadest to narrowest, the sequence is: "the 1883 eruption of the volcano Krakatau" → "the effect of Krakatau's eruption on global temperatures" → "temperature drops in Europe due to Krakatau's eruption")
