Which of the following can be inferred about people who depend on fishing?
Along the Pacific coast of South America runs a cold ocean current named after the scientist Alexander von Humboldt. Its water rises from the depths carrying nutrients, and these feed tiny plants that in turn feed small fish such as anchovies. For this reason the coast of Peru has long been one of the richest fishing areas in the world. Every few years, however, the sea surface warms and the nutrient supply drops sharply. This event, known as El Nino, drives the anchovies away to deeper or more distant waters, and catches fall. Fishing communities must then rely on other income until conditions return to normal.
Answer and explanation
Correct answer: B. They face periods of lower income that they cannot fully control
- Step 1: The passage says communities must rely on other income until conditions return to normal.
- Step 2: This implies their income drops in some years because of ocean conditions.
Answer
They face periods of lower income that they cannot fully control.
Why not the others: The passage says nothing about moving to cities or preferring El Nino, and it shows they are affected by the ocean.
