The author uses a cause/effect text structure to demonstrate the dangers of cosmic radiation. The text explains how cosmic rays can lead to changes in the physical architecture of the brain's nerves, which in turn can harm memory. This structure effectively illustrates the consequences of exposure to cosmic radiation for astronauts in deep space.
by Nsikan Akpan One day, space explorers might stroll along the red rocks of Mars. But radiation exposure during the trip may wipe away their memories of home. A new report says that cosmic rays can change the physical architecture of the mind's nerves, harming the brain regions that govern memory. Cosmic rays, comprised of high-speed atomic particles, blanket the Milky Way galaxy. The radiation constantly bombards our planet, but the Earth's magnetic field and its atmosphere save us from the most dangerous rays. People who venture into deep space aren't so lucky, as cosmic rays can easily penetrate a spaceship's metallic hull or a space helmet. So before NASA sends anyone into deep space, they want to figure out the possible long-term ramifications of exposure to cosmic radiation.
Use the excerpt to answer the question. Why does the author use a cause/effect text structure? (1 point) to demonstrate the dangers of cosmic radiation to explain the importance of space travel to propose solutions to memory loss to offer alternatives to space helmets
