Parajumbles Question 5 - CAT 2020
Question
- Look forward a few decades to an invention which can end the energy crisis, change the global economy and curb climate change at a stroke: commercial fusion power.
- To gain meaningful insights, logic has to be accompanied by asking probing questions of nature through controlled tests, precise observations and clever analysis.
- The greatest of all inventions is the ĂĽber-invention that has provided the insights on which others depend: the modern scientific method.
- This invention is inconceivable without the scientific method; it will rest on the application of a diverse range of scientific insights, such as the process transforming hydrogen into helium to release huge amounts of energy.
Step-by-Step Explanation
- Correct Sequence: 3214
- Explanation: Sentence 3 serves as the master topic sentence, naming the modern scientific method as the greatest "ĂĽber-invention" of humanity. Sentence 2 expands on the components of this method, explaining that it uses logic backed by controlled tests and precise observations. Sentence 1 shifts from the general method to a grand, futuristic application of it: commercial fusion power. Sentence 4 locks the paragraph together by opening with the demonstrative pointer "This invention...", which traces directly back to the fusion power technology described in sentence 1, noting that it would be completely inconceivable without the scientific method.
- FundaMakers Tip: Tracking Demonstrative Pronoun References. Always check exactly what a phrase like "This invention" is pointing toward. It cannot map to the scientific method (which is an intellectual framework, not an individual machine or technical invention). It targets the specific technological system mentioned in sentence 1 ("commercial fusion power"), creating an explicit 1-4 chain.
