Question

How does the author unfold the idea that the mountain pine beetles are a major threat to the lodgepole pine trees? a) First, the author describes the life cycle of the mountain pine beetles. b) Then, the author explains the ecological impact of their infestation. c) First, the author presents scientific research on beetle behavior. d) Then, the author discusses the economic consequences of their presence.

Answer 1

The author unfolds the idea that mountain pine beetles are a major threat to lodgepole pine trees by describing the beetles' life cycle, explaining their ecological impact, and discussing the economic consequences of their presence.

Step-by-step explanation:

To unfold the idea that mountain pine beetles are a major threat to lodgepole pine trees, the author takes the following approach:

First, the author describes the life cycle of the mountain pine beetles, providing information about their reproductive behavior and ability to infest trees.

Then, the author explains the ecological impact of the infestation, highlighting how the beetles kill a large proportion of the trees in affected forests.

Finally, the author discusses the economic consequences of the beetles' presence, emphasizing the challenges faced by forest management and fire management due to the extensive damage caused by the beetles.

Answer 2

The correct sequence is:

c,b,d,a

To understand how the author unfolds the idea that mountain pine beetles are a major threat to lodgepole pine trees, we can examine the sequence of information provided in the text. The correct sequence is as follows:

c) First, the author presents scientific research on beetle behavior.

b) Then, the author explains the ecological impact of their infestation.

d) Finally, the author discusses the economic consequences of their presence.

a) The author does not necessarily need to describe the life cycle of the mountain pine beetles first in this context, as the primary focus is on the threat they pose to lodgepole pine trees, and scientific research, ecological impact, and economic consequences are more directly related to conveying this threat.
