1. The primary purpose of the passage is to explain the
C. reasons that a phenomenon benefits a particular organism - "Even more than mountainside slides of mud or snow, naturally occurring forest fires promote the survival of aspen trees"
2. It can be inferred from the passage that when aspen groves experience a "disturbance" , such a disturbance
A. leads to a hormonal imbalance within an aspen clone - But when the stem dies, its hormone signal also ceases. If a clone loses many stems simultaneously, the resulting hormonal imbalance triggers a huge increase in new, rapidly growing shoots that can outnumber the ones destroyed.
3. The author of the passage refers to "the bark of most trees" (line 6) most likely in order to emphasize the
A. vulnerability of aspens to damage from fire when compared to other trees - Correct
4. According to the passage, which of the following would occur if an aspen grove failed to regenerate periodically?
D. The grove would lose its access to sunlight - Correct - An aspen grove needs to experience fire or some other disturbance regularly, or it will fail to regenerate and spread. Instead, coniferous trees will invade the aspen grove's borders and increasingly block out sunlight needed by the aspens.
