Problem-Solution Structure and Tone in an Informational Text Answers

Read the excerpt from Chapter Three of Windows to the Universe: Revolutions in Astronomy.The discovery of infrared light opened new doors for astronomers, allowing them to see beyond what was possible with visible light. However, even with advancements in telescope technology, the Earth's atmosphere still poses significant challenges. To overcome issues like atmospheric distortion and light pollution, astronomers needed to take a huge leap forward and get telescopes beyond Earth. This led to the development of space telescopes.

Read the excerpt from Chapter Three of Windows to the Universe: Revolutions in Astronomy.Refracting telescopes, which use lenses to gather and focus light, need lenses made from pure, bubble-free glass. These lenses must be ground and polished with great precision. Reflecting telescopes require mirrors shaped into precise parabolic curves. Any mistake in shaping or polishing the lenses or mirrors could result in blurry images.How does the author create an informative tone in this excerpt?

Read the excerpt from Chapter Three of Windows to the Universe: Revolutions in Astronomy.The construction and launch of Hubble faced many setbacks. Funding was a constant issue, with NASA and Congress debating the budget. One key figure, Dr. Nancy Grace Roman, played a vital role in securing funding and keeping the project on track. Dubbed the "Mother of Hubble," Dr. Roman was NASA's first Chief of Astronomy and a strong advocate for space-based telescopes. Without her dedication, Hubble might never have left the ground.

Read the excerpt from Chapter Three of Windows to the Universe: Revolutions in Astronomy.The Hubble was a creation born of cooperation. Originally intended to last 15 years, Hubble has exceeded all expectations, celebrating its 30th anniversary in 2020. Its remarkable scientific contributions have paved the way for new space telescopes and inspired a new generation of astronomers.Hubble's success is a testament to human ingenuity, determination, and the desire to understand the universe. The images it has given us have fundamentally changed how we view our place among the stars, and its legacy will continue to inspire future explorations of the cosmos.

Which is a problem-solution signal word?

Read the excerpt from Chapter Three of Windows to the Universe: Revolutions in Astronomy.One of Hubble's most famous images is the Hubble Deep Field, which reveals thousands of galaxies in a tiny part of the sky. By examining this image, scientists could see galaxies billions of light-years away, providing a glimpse of what the universe looked like in its early stages. The Hubble Space Telescope has helped answer many questions, but it has also created new mysteries about dark matter, dark energy, and the formation of galaxies.

Read the excerpt from Chapter Three of Windows to the Universe: Revolutions in Astronomy.As humanity's curiosity about the universe grew, so did the need for more powerful tools to observe the cosmos. However, early telescopes faced many challenges, such as blurry images and atmospheric interference. Solving these problems eventually led to one of the most groundbreaking tools ever created: the Hubble Space Telescope.
