Reading the passage
Only 9.5 millimeters in a century—that's slow. The example gives us a concrete sense of the time represented by lichen growth. It helps us see how measuring something on a rock today can tell us about a rockfall long ago.
Working the answers
- A
Establishing a colony quickly and expanding slowly are different things. This number describes the slow outward growth, not the speed of initial colonization.
- B
Slow doesn't mean among the slowest known. We aren't given growth rates for other species to make that ranking.
- C
The example gives a growth rate; it doesn't compare environmental conditions or show how a change in those conditions alters the rate.
- D
Nothing in the example derives the 500-year limit mentioned later. It illustrates the timescale of growth, not why the method works best within that particular period.
- ECorrect
The number makes “slow but constant” growth concrete: a small outward increase represents an entire century. That is the timescale researchers use when working backward from lichen size to the timing of a rockfall.
