Official answer
Word before: They | Word Omitted: are | Word after: released — required to complete the passive construction 'They are released...' with a plural, present-tense subject.
Marking scheme
- 1.1 mark only if the correct missing word 'are' is given AND placed correctly between 'They' and 'released' (i.e. before: They, after: released). No mark for the word without the before/after context, and no mark for a wrong auxiliary such as 'were' or 'is'.
Hint
The past participle 'released' + 'from' signals passive voice — a plural, present-tense auxiliary 'be' is missing before it.
Quick oral answer
The missing word is 'are': 'They are released mainly from...' — 'released' with 'from' is passive voice, and the plural present-tense subject 'They' needs the auxiliary 'are'.
Common mistakes
- 1.Reading 'released' as a complete active past-tense verb and leaving the line unchanged, missing the passive-voice auxiliary.
- 2.Inserting 'were' or 'is' instead of 'are' — 'were' is wrong tense (passage is present) and 'is' is singular, but the subject 'They' is plural.
Analysis and explanation
Word-omission (editing) task: identify the missing auxiliary that completes a passive-voice verb.
Concept
- Line: 'They released mainly from' → reconstructed as 'They are released mainly from burning fossil fuels.'
- 'released ... from' signals passive voice (be + past participle), and the auxiliary 'be' has been dropped.
Key points
- Subject 'They' (= greenhouse gases) is plural; paragraph is in simple present → correct auxiliary is 'are'.
- CBSE format demands the word immediately before and after the missing word, not just the word itself.
Common mistakes
- Reading 'released' as a complete past-tense active verb and leaving the gap unnoticed, or inserting the wrong tense ('were').
Real-world
- Reinforces that greenhouse gases are continuously released by human activity (burning fossil fuels), a key fact in climate-change writing.

Interesting facts
Omission questions almost always target 'small' function words — articles, prepositions, auxiliaries, or conjunctions — because these are the words the eye skips most easily while reading.
The passive voice (be + past participle) is very common in scientific/factual writing like this climate paragraph, which is exactly why the missing auxiliary 'are' fits the register.

Frequently asked questions
How do I write the answer in the correct format?
You must give three parts: the word before, the missing word, and the word after. For line (i) it is — Word before: They, Missing word: are, Word after: released.
Why 'are' and not 'were'?
The whole paragraph is written in the simple present tense (gases 'trap' heat, 'leads to' global warming). So the passive must also be present: 'are released', not the past 'were released'.
