The weakened ozone .........., which is vital to protecting life on Earth, is on track to be restored to full strength within decades.
پاسخ صحیح: گزینهٔ A — layer
پاسخ تشریحی
Answer: option 1 — layer (لایه). Ozone layer (لایهٔ اُزون) is the established noun combination for the atmospheric region containing ozone that protects life on Earth.
| Option | Meaning | Persian gloss |
|---|---|---|
| 1) layer | a sheet, stratum, or thickness of material | لایه |
| 2) level | an amount, degree, or height | سطح، میزان |
| 3) brim | the upper edge of a container; the projecting edge of a hat | لبهٔ ظرف، لبهٔ کلاه |
| 4) ingredient | a component used to make a mixture or product | مادهٔ تشکیلدهنده |
The relative clause about protecting life on Earth, together with weakened and restoration, identifies the protective atmospheric layer.
- Level can describe ozone concentration, but the usual wording is ozone levels rising or falling. This sentence identifies a weakened protective structure, the ozone layer.
- Brim is an edge; it would fit a cup or a hat, not an atmospheric region.
- Ingredient is a constituent of a mixture; the stem does not describe a recipe or product composition.
Exam trick: A familiar scientific collocation can decide a vocabulary item. Distinguish ozone layer (the protective region) from ozone level (the measured amount).
