DISCUSSION: Line 32 implies that minor eruptions are not “dust-spitting explosions”.
___________
- “Less” is a vague term. An eruption that produced 2% less lava might still be a major eruption.
- Same as A. The impact could be 1% smaller.

- CORRECT. Exactly. There’s no firm dividing line, but minor eruptions spew less dust and therefore have little to no effect on the atmosphere.
- This isn’t strong enough. Mass and Portman say that minor eruption have no effect on temperature (lines 30-31).
