Zorluk: KolayDrawing Logical Inferences from Passage Premises

Passage:
Ecologists studying avian migration patterns in North America observed that songbirds migrating during autumn rely heavily on high-fat berries produced by native shrubs along coastal stopover sites. In areas where invasive non-native plant species replaced native flora, the fruit available contained significantly lower lipid concentrations. Consequently, songbirds spending extended time at stopover sites dominated by non-native plants gained weight at a slower rate than those resting in native-dominated habitats, despite consuming equal volumes of fruit.

Statement: Based on the passage premises, a songbird feeding exclusively on non-native fruit would require more time to achieve a target weight gain than a songbird consuming an equal daily volume of native fruit.

Cevap: Cevap

Cevap

True
The statement logically follows from the premises given in the passage. The text states that songbirds consuming equal volumes of non-native fruit gain weight at a slower rate. Therefore, if daily volume consumed is kept equal, achieving a given total weight gain must take longer for a bird relying on non-native fruit.

Adım Adım Çözüm

1
Identify the relationship between fruit type, lipid concentration, and weight gain rate established in the premises.
Non-native fruit has lower lipid concentration, causing songbirds to gain weight at a slower rate when equal volumes are consumed.
This establishes the fundamental rate premise linking fruit intake volume to weight gain.
2
Apply the premises to the scenario described in the statement where daily consumption volume is equal.
Because the rate of gain per volume is lower for non-native fruit, accumulating a specific total amount of weight gain at an equal daily volume of intake requires more time.
A lower rate of accumulation for a fixed daily input logically necessitates a longer time interval to reach a constant target threshold.
