The answer is the fourth one: mantle.

Explanation for each option:

  • Outer core: The outer core is a layer of molten metal, primarily iron and nickel, that surrounds the inner core. It is not characterized as a layer of soft, hot rock.
  • Crust: The crust is the outermost layer of Earth, composed of solid rock. It is not soft and is relatively cool compared to the deeper layers.
  • Inner core: The inner core is a solid sphere composed mainly of iron and nickel. It is extremely hot but not soft.
  • Mantle: The mantle is the layer of Earth located between the crust and the outer core. It is composed of hot, solid rock that behaves plastically over long periods, allowing it to flow slowly. This makes it the best characterization of a layer of soft, hot rock.

Summary: The mantle is the layer of Earth best characterized as a layer of soft, hot rock.

Consider the following argument: 1. Statement: All vineyard owners grow grapes. 2. Statement: Anthea grows grapes. 3. Conclusion: Anthea owns a vineyard. Draw an Euler diagram for this argument and determine whether it is valid or invalid. Select the answer and correct reason from the list below. Select the correct answer below: Valid because Anthea is a member of both the set "people who grow grapes" and the subset "vineyard owners". Valid because Anthea owns a vineyard. Invalid because we do not not know if Anthea is a member of both the set "people who grow grapes" and the subset "vineyard owners". Invalid because it is not a syllogistic argument.
