stainless steel is a metal alloy that combines the most desirable properties of two metals: steel and chromium. though steel alone exhibits strength, it is subject to corrosion when exposed to moisture. steel containing at least 12 percent chromium retains its strength and flexibility but gains the attribute of being corrosion resistant. the presence of chromium in stainless steel forms a very thin layer of chromium oxide on its surface. this barrier staves off corrosion, sealing off the stainless steels internal structure. this feature makes stainless steel ideal for a vast number of applications in industries as diverse as aviation, food preparation, and medicine. do it! the combination is ________. a beneficial b expendable c grotesque d abrasive

Answer

Brief Explanations:

The text states that stainless steel (the combination of steel and chromium) retains strength and flexibility and gains corrosion - resistance. It also mentions that this makes it ideal for many applications. So, the combination has positive effects.

  • Beneficial means having a good effect or being helpful.
  • Expendable means able to be used up or replaced, which is not relevant here.
  • Grotesque means ugly or distorted in a strange way, which is incorrect.
  • Abrasive means rough or harsh, which is not in line with the description of the combination.

Answer:

A. beneficial
