In the following questions choose the word which is the exact OPPOSITE of the…

Answer: Solid

Explanation:

The word "hollow" means empty or having an internal cavity. The exact opposite is "solid," which means not hollow — full throughout or without a cavity.

• Why "solid" is correct: "Solid" directly contrasts with "hollow" because it implies no internal empty space.

• Why the other choices are not exact opposites:

  • "Filled": Close in meaning but can describe something placed into a hollow space; it does not always imply the object itself has no cavity.

  • "Strong": Relates to strength or durability, not to whether something is hollow or solid.

  • "Substantial": Means large or considerable; it does not address the presence or absence of an internal cavity.

• Other common antonyms: solid, full, convex.
