koban [17]

Hello. You forgot to show the text and answer options. Both are set out below.

In 2002, astronomers using Hubble noted that the abundance of high-altitude clouds increased the planet's brightness from observations made in the late 1990s. Astronomers consider this brightness increase a sign of seasonal change. Hubble studies show that Neptune has a nearly constant brightness at low latitudes (near the equator). This supports the idea that the observed changes are seasonal in nature, because seasonal effects would be minimal near the equator and most evident at high latitudes.

A. to prove how scientists were able to confirm that Neptune has recurring weather

B. to suggest that Neptune is similar to Earth in terms of weather patterns

C. to demonstrate how scientists were able to conclude that Neptune has clouds like Earth

D. to introduce the idea that Neptune is similar to other planets in the galaxy

Answer:

A. to prove how scientists were able to confirm that Neptune has recurring weather

Explanation:

The text presents how scientists came to the conclusion that Neptune is a planet that has seasonal changes, similar to the earth, but with a different time interval between them. The text also shows that it is possible to observe these seasonal changes with the increase in the latitude at which the planet is observed, which reinforces the idea that, on this planet, the climate is recurrent, according to seasonality.
