Zorluk: KolayParaphrased Fact Recognition

Wildland firefighters carry compact, aluminized fire shelters designed as a emergency safety measure in entrapment situations. When deployed, the shelter's outer foil reflects radiant heat away from the occupant, while an inner fiberglass layer prevents thermal energy from transferring inward. Because convective heat from hot draft gases can compromise the structure, firefighters are trained to clear ground fuel and pin the shelter's edges firmly against bare dirt. Fastening the perimeter securely to the soil prevents rising embers and superheated air from entering the breathable space underneath.

According to the passage, why must the edges of a deployed fire shelter be held tightly against the ground?

  1. A
    To reflect radiant heat away from the occupant
  2. B
    To allow hot draft gases to enter and ventilate the shelter
  3. To stop extremely hot air and sparks from penetrating beneath the coverCevap
  4. D
    To extinguish the surrounding forest fire by cutting off oxygen to the flames

Cevap

The edges are secured against the ground to stop extremely hot air and sparks from penetrating beneath the cover.
The passage explicitly explains that securing the perimeter to the dirt prevents rising embers and superheated air from reaching the interior. The correct answer accurately restates this factual detail using synonyms, replacing 'rising embers' with 'sparks' and 'superheated air' with 'extremely hot air.'

Adım Adım Çözüm

1
Locate the portion of the text discussing holding or fastening the shelter edges to the ground.
The final sentence states: 'Fastening the perimeter securely to the soil prevents rising embers and superheated air from entering the breathable space underneath.'
Direct fact identification is necessary before identifying its paraphrased equivalent.
2
Translate key terms from the sentence into synonymous expressions.
'Fastening the perimeter securely' corresponds to 'edges held tightly', 'prevents ... from entering' corresponds to 'stop ... from penetrating', and 'rising embers and superheated air' corresponds to 'extremely hot air and sparks'.
Paraphrased fact recognition requires matching meaning rather than exact phrasing.
3
Select the option that matches this restated meaning while rejecting verbatim and inverted traps.
The option stating that it stops extremely hot air and sparks from penetrating beneath the cover is confirmed as the correct answer.
This option accurately captures the cause-and-effect relationship using restructured phrasing.
