Question

question 8 (1 point)
if something is concrete, then it is
an object that can be understood by everyone.
a single, individual object.
a visible, touchable object.

Explanation:

To determine the correct answer, we analyze the definition of "concrete". A concrete object is typically defined as something that is tangible, meaning it can be seen and touched. The first option is incorrect because not all concrete objects are understood by everyone (e.g., a complex machine part might not be understood by all). The second option is incorrect as concrete objects can be part of a group or multiple objects (e.g., a pile of concrete blocks). The third option matches the definition of a concrete object as visible and touchable.

Answer:

C. a visible, touchable object.
