Answer:

concrete

Explanation:

Researchers think regolith on Mars could serve as a replacement for concrete components. The Mars rovers have used gas chromatography, mass spectrometry, and laser spectrometry to determine the composition of martian soil. Mars regolith is mostly silicon dioxide and ferric oxide, with a fair amount of aluminum oxide, calcium oxide, and sulfur oxide. The composition varies from place to place on the planet’s surface because of variability in asteroid collisions and the weathering by wind and water, in ancient oceans and in some modern water flows. But no spacecraft has returned to Earth with actual samples of the material.

Reread lines 40-54 of "The Wanderer." To whom or what does the phrase alone

Vsevolod [243]

The phrase applies to an exiled man.

We can reach this conclusion because:

"The Wanderer" is an Anglo-Saxon poem that portrays the disadvantages of being an exiled person.
The poem presents a man who has been removed from his people and now walks without any company.
The poem shows how difficult this life of solitude is, because, besides the lack of company, man lives without love and no one to count on.
However, this man has great faith and believed that all the suffering he is experiencing will pass one day.
