- In the following paragraph, one word has been omitted in each line. (iii) gases leads global warming and climate change.
Word before: leads | Word Omitted: to | Word after: global — the verb 'lead' (meaning 'result in') is always followed by the preposition 'to'.
Marking Scheme
- 11 mark only if the missing word 'to' is given AND correctly placed between 'leads' and 'global' (before: leads; after: global). No mark for the word without the before/after context, and no mark for inserting any other word (e.g. 'the').
Hint
The verb 'lead' meaning 'to result in' always takes a preposition before its outcome — which small word links 'leads' to 'global warming'?
Quick Oral Answer
The missing word is 'to': 'gases leads to global warming and climate change' — the verb 'lead' in the sense of 'result in' must be followed by the preposition 'to'.
Analysis & Explanation
Word-omission task testing the fixed verb + preposition pattern 'lead to'.
Concept
- Line: 'gases leads global warming and climate change' → reconstructed as '...leads to global warming and climate change.'
- The verb 'lead' meaning 'to cause/result in' is always followed by the preposition 'to'.
Key points
- Without 'to', 'leads' sits directly (and ungrammatically) before the noun phrase 'global warming'.
- Note: 'leads' stays singular because its true subject is the singular 'An increase' (not the omitted word, just background agreement).
- CBSE format: word before = 'leads', word after = 'global'.
Common mistakes
- Inserting an article like 'the' instead of the preposition, or leaving the sentence unchanged.
Real-world
- Rising greenhouse gases genuinely 'lead to' global warming and climate change — a core cause-effect fact in environmental science.
Common Mistakes
- 1Inserting an article such as 'the' before 'global warming' instead of the required linking preposition 'to'.
- 2Leaving the line unchanged, not noticing that 'leads global warming' is missing the preposition that the verb 'lead (to)' demands.

Interesting Facts
'Lead to', 'result in', 'give rise to' and 'contribute to' are all cause-effect expressions that must keep their preposition — dropping it is a very common editing-question target.
The verb 'leads' is deliberately singular here because the real subject is 'An increase' (singular), a neat reminder that the subject is the head noun, not the nearest noun 'gases'.

Frequently Asked Questions
Why is the missing word 'to' and not 'the'?
The verb 'lead' meaning 'to result in' takes the preposition 'to' before its outcome — 'leads to global warming'. An article like 'the' would not complete the verb's required pattern.
Is the singular verb 'leads' a mistake?
No. The subject is 'An increase in greenhouse gases', whose head noun 'increase' is singular, so 'leads' is correct. That verb is not the omitted word; the omitted word is the preposition 'to'.
