Question

answer the questions based on your reading of this magazine excerpt. what is the main issue with controlled burns? the cost is too high. what changes too quickly to predict? the weather which word is a clue to how the writer feels? the light burners proposed to \control\ the destructiveness of the deliberate firing by burning the woods in the spring or fall when sufficiently moist to prevent the fire from seriously injuring either old timber or young trees. a careful study of the area... shows that such control amounts to little or nothing. the light burners ignore... the rapidity with which... sunlight in warm weather dries up the litter in the pine woods. a south slope will be so dry as to make any fire exceedingly hot and destructive before a north slope will burn at all. areas which will burn but lightly and irregularly early in the morning will flare up and consume in the most approved fashion by mid - afternoon. the moisture following light spring or fall rains often disappears so rapidly that the period of \safe\ burning is a matter of hours, not of days. actually to burn the western pineries, as the advocates of this theory propose to burn them, would, if it could be done at all, entail a cost for effective control many times greater than the cost of an efficient

Explanation:

The text discusses controlled burns. For the first question, the text mentions that “if it could be done at all, entail a cost for effective control many times greater than the cost of an efficient” which indicates the main issue is cost. For the second, it talks about how “the moisture following light spring or fall rains often disappears so rapidly” and weather - related factors like sunlight drying the litter, showing weather changes quickly. For the third, “ignore” shows the writer’s negative view as the light burners are disregarding important factors.
