Question

ojibwe people have always had a relationship with the land they live on. they hunt and fish for food. living off the land requires the ojibwe to pay close attention to the seasons. they have to be ready when the plants and animals tell them that it’s time. for example, each spring, when the water temperature of the lakes is between 42 and 50 degrees fahrenheit, freshwater fish called walleye move to the shores to lay their eggs. this signals the right time to begin harvesting fish. today, ojibwe people still use a traditional method called spearing to harvest walleye. and like their ancestors, they fish at night. in order to see the fish, they shine a light into the water. before flashlights were invented, spearfisher used a lit torch. the eyes of the walleye, or agaa, shine in the light, making them easier to spot. that is how the practice got the name waswaagoing. this means “fishing by torchlight.”
why must the ojibwe people pay close attention to the seasons?
they only fish during the warmest times of the day.
they must know the right time of year for gathering certain foods.
they must be ready to move to a new place where they can hunt.
they still catch walleye with the spearing method.

Explanation:

Para determinar por qué los ojibwe deben prestar atención a las estaciones, se analiza el texto: menciona que deben estar listos cuando las plantas y animales les indican el momento (por ejemplo, la llegada de la primavera y la temperatura del agua para la pesca del walleye). Esto se alinea con la opción "They must know the right time of year for gathering certain foods" (Deben saber el momento adecuado del año para recolectar ciertos alimentos), ya que la atención a las estaciones les permite conocer cuándo cazar, pescar o recolectar según la disponibilidad de recursos.

Answer:

They must know the right time of year for gathering certain foods.
