Information and Ideas practice question
Sea glass is nothing more than broken bottle glass that the sea has tumbled smooth over decades. Its frosted surface comes from years of salt water slowly leaching minerals out of the glass, so the more frosted a piece is, the longer it has been in the water.
Which choice best states the main idea of the text?
- A. Sea glass is ordinary broken glass transformed by long exposure to the sea.Correct
- B. Sea glass is a rare mineral formed on the seabed.
- C. Frosted glass is manufactured to look as if it came from the sea.
- D. The sea breaks bottles into dangerously sharp pieces.
Answer: A. Sea glass is ordinary broken glass transformed by long exposure to the sea.
The text says what sea glass is (broken bottles) and what the sea does to it (smooths and frosts it over time). Choice A captures both.
Why the other answers are wrong
- B. Sea glass is a rare mineral formed on the seabed.
- The text says it is broken bottle glass, not a mineral.
- C. Frosted glass is manufactured to look as if it came from the sea.
- Nothing is manufactured; the frosting comes from the sea.
- D. The sea breaks bottles into dangerously sharp pieces.
- The text describes the sea smoothing glass, not sharpening it.
