Directions for the following item:
Read the following passage and answer the items that follow the passages. Your answers to these items should be based on the passages only .

Scientists studied the vernal window transition period from winter to the growing season. They found that warmer winters with less snow resulted in a longer lag time between spring events and a more protracted vernal window. This change in the spring timetable has ecological, social and economic consequences for agriculture, fisheries and tourism. As the ice melts earlier, the birds don't return, causing a delay, or lengthening in springtime ecological events.

With reference to the above passage, the following assumptions have been made ;

1. Global warming is causing spring to come early and for longer durations.

2. Early spring and longer period of spring is not good for bird populations.

Explanation:

The correct answer is: 1. 1 only

Let’s evaluate each assumption based on the passage:

Assumption 1: Global warming is causing spring to come early and for longer durations.
Correct – The passage states: “They found that warmer winters with less snow resulted in a longer lag time between spring events and a more protracted vernal window.” This implies that warmer conditions (i.e., global warming) are affecting the timing and duration of spring.

Assumption 2: Early spring and longer period of spring is not good for bird populations.
Incorrect/Not directly stated – The passage mentions: “As the ice melts earlier, the birds don't return, causing a delay, or lengthening in springtime ecological events.” While this implies a disruption in timing, it does not explicitly state that it is harmful to bird populations — only that there’s a mismatch or delay in events.
