Validating assumptions regarding wildlife protection laws

Reading Comp.Environment / Ecology passageStatement-basedMedium

Question

Based on the above passage, the following assumptions have been made:

1Giant icebergs have a bearing on primary productivity and food chains of the Southern Ocean.
2Melting of giant icebergs can produce climate change effects and impact world fisheries.

Options

a

1 only

Answer
b

2 only

c

Both 1 and 2

d

Neither 1 nor 2

Explanation

Assumption 1 is explicitly valid because the text notes icebergs spur "phytoplankton growth," which represents primary productivity and forms the base of ocean food chains[cite: 1903, 1904]. Assumption 2 introduces a speculative leap regarding "world fisheries" and macro "climate change effects". While phytoplankton affects carbon storage, the passage stays restricted to the Southern Ocean's ecological metrics and provides no data to support broad assertions about global industrial fishing[cite: 1903, 1904].

Guard against validating assumptions that scale up local or regional biological observations into worldwide commercial or climate conclusions.

Answer: (a).
