Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the low pressure system to the high pressure system, causing wind. The wind will carry moisture since it is coming from the ocean. Choose the statement which corrects the error(s) in Jennifer's prediction.


a weather map of Florida with an L to the left of Florida over the ocean and an H over the land


a The wind from the ocean will not carry moisture.

b The wind will travel from the high pressure system to the low pressure system.

c Since the low pressure system is not over land, wind will not be created.

d Wind is only created when two high pressure systems meet.

The local newspaper has published the passage below.

Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.

Which statement in the news passage above is inaccurate?

The aurora australis cannot be seen from space.
The Hubble telescope does not orbit our planet.
The aurora australis is known as the northern lights.
Solar winds do not reach well beyond our planet.
