2025 CSAT — Q1
Passage
Maintaining an ecosystem just to conserve biodiversity will affect its commercial potential as well as the livelihoods dependent on the ecosystem. There is also a conflict between using an ecosystem only for livelihoods, for commercial exploitation, or strictly for conservation. Deforestation caused due to commercial exploitation will lead to indirect harm like floods, siltation problems and microclimatic instability, apart from adversely affecting livelihoods dependent on forests. These conflicts are particularly acute in developing countries where the dependence of people on the ecosystem is significant, and commercial exploitation has the potential to boost national income.
Which one of the following statements best reflects the critical message conveyed by the author of the passage?
Thinking pathway
Locate. This asks for the central idea, so do not pick the option that sounds the grandest — find the thesis the whole passage is built to support by naming the word the author keeps returning to. Read the through-line, not a single sentence. Here the recurring load-bearing word is conflict: “There is also a conflict between using an ecosystem only for livelihoods… These conflicts are particularly acute in developing countries.” That line is the anchor.
Test — thesis, not detail; and check the fit. A central-idea key must (i) paraphrase the thesis, not a supporting detail, and (ii) say no more and no less than the author. Hold each option against the through-line — “livelihood-dependence and ecosystem-degradation occur together and aggravate each other, producing conflict.” Only (c) restates exactly that. The rest either shrink it to a detail, add a verdict the author never gives, or invert it.
Eliminate by anatomy. (d) over-states the case — a gist-trap that bolts an absolutist verdict (“completely stopped”) onto a passage that only describes a conflict; on a central-idea question, an option more extreme than anything the author asserts is almost always wrong. (a) gets the direction backwards — it states the opposite of the author’s stance (that conservation does not matter). (b) is out of scope — it imports a “fundamental rights” frame the passage never raises. Each is wrong from the text, not merely “less good.” Key: (c).
Evidence in the text
“There is also a conflict between using an ecosystem only for livelihoods, for commercial exploitation, or strictly for conservation… These conflicts are particularly acute in developing countries where the dependence of people on the ecosystem is significant.” The whole passage frames the co-occurrence of livelihood-dependence and ecosystem-degradation as mutually aggravating, ending in “conflicts.”
Worked rationale
Find the thesis the whole passage is built to support, not a true side-detail. The passage’s through-line is: an ecosystem is pulled three ways (conservation, livelihoods, commerce); these pulls conflict; commercial exploitation harms both the ecosystem (floods, siltation) and the livelihoods that depend on it; and this is worst where dependence is high. The load-bearing word the author keeps returning to is conflict — the simultaneous pursuit of livelihood and the resulting degradation feed each other.
(c) captures exactly this: livelihood-sustenance and ecosystem-degradation, occurring together, exacerbate one another, leading to conflicts and imbalance. That is the critical message.
Answer: (c).
Why the other options miss
- A cause and effect reversed: it inverts the passage. The author says conservation does matter and
- B out of scope: “fundamental rights” appears nowhere. The passage discusses harm and conflict, never a rights claim. True-sounding, textually unsupported.
- D too strong: “completely stopped” is an absolutist prescription the passage never makes. The author describes a conflict to be navigated, not a verdict to ban commerce.
Specialist insight
A central-idea question is won by separating the thesis from a true-but-narrow detail and by distrusting the absolutist option. Here (d) is the classic trap for a gist-reader: it sounds like a strong “main message,” but “completely stopped” is a claim the passage never licenses — and on a central-idea question, an option more extreme than anything the author actually says is almost always wrong. The reading move: name the author’s recurring word (conflict) and pick the option that restates it without adding a verdict or a new concept.
(d) "completely stopped" is the over-strong gist-trap; the passage describes a conflict to navigate, not a ban to impose.
