Difficulty: MediumExplicit Details

Sociable weavers (*Philetairus socius*) construct massive compound community nests that can house hundreds of birds. A study analyzed the internal temperature of these structures and found that the central chambers of the nest maintain a remarkably stable temperature, remaining warmer than the surrounding air during cold desert nights and cooler during the peak heat of the day. This thermal buffering is achieved through the nests' large bulk and thick straw walls, which insulate the inner chambers. However, the outer chambers fluctuate in temperature similarly to the exterior environment, offering little thermal regulation. Thus, only the nesting pairs occupying the interior rooms benefit from this energy-saving microclimate.

Based on the text, what is true of the temperature in different areas of a sociable weaver nest?

  1. A
    The entire compound nest maintains a stable temperature that is completely insulated from the outside environment.
  2. The temperature in the central chambers is more stable than the temperature in the outer chambers.Answer
  3. C
    Nesting pairs actively adjust the thickness of the straw walls to control the temperature of the outer chambers.
  4. D
    The sociable weavers construct the massive nests primarily to protect their food storage from temperature extremes.

Answer

The correct answer states that the temperature in the central chambers of the nest is more stable than the temperature in the outer chambers.
The correct answer shows that the temperature in the central chambers of the nest is more stable than the temperature in the outer chambers. This is directly supported by the text, which states that the central chambers maintain a 'remarkably stable temperature,' whereas the outer chambers 'fluctuate in temperature similarly to the exterior environment, offering little thermal regulation.'

Step-by-Step Solution

1
Read the question carefully to identify the core information being asked about.
The question asks what the text states is true about the temperatures in different parts of a sociable weaver's nest.
Understanding the focus of the question guides the search for specific details in the text.
2
Locate and analyze the sentences describing the temperature of the central and outer chambers.
The text states that the central chambers maintain a 'remarkably stable temperature' while the outer chambers 'fluctuate in temperature similarly to the exterior environment.'
This direct comparison allows for the identification of a factually supported statement.
3
Evaluate the response options against the located evidence.
The statement indicating that the temperature in the central chambers is more stable than in the outer chambers is directly supported, while the other options contradict the text or introduce unsupported speculations.
Matching the options directly to the text ensures a correct, evidence-based selection.
