Introduction
Critical Reasoning RC questions में आपको लेखक के argument को समझना और evaluate करना होता है-सिर्फ passage पढ़ना पर्याप्त नहीं होता। ऐसे question types (Assumption, Strengthen, Weaken) CAT VARC, GMAT, और Bank PO Mains में बहुत common हैं। ये आपकी यह क्षमता जांचते हैं कि आप conclusion पहचान सकें, उसे support करने वाली logic समझ सकें और यह evaluate कर सकें कि नई जानकारी argument को मजबूत करती है या कमजोर।
Pattern: Critical Reasoning RC
Pattern
मुख्य उद्देश्य यह पहचानना है कि लेखक का conclusion क्या है, उसे support करने वाली reasoning क्या है, और कौन-सा statement उस reasoning के लिए आवश्यक, helpful या harmful है।
Step-by-Step Example
Question
Over the past decade, several metropolitan cities have expanded their public bicycle-sharing programs,
arguing that these systems help reduce traffic congestion, improve air quality, and promote healthier
commuting habits. A 2023 study by the Urban Mobility Institute (UMI), however, questions the extent of
these benefits. The study found that while bicycle usage increased by nearly 40% after new stations were
installed, a majority of the additional users shifted from walking or using public buses-not from private
cars. As a result, UMI concludes that the impact on traffic congestion has been overstated.
The report further suggests that policymakers should re-evaluate the allocation of funds toward
bicycle-sharing expansions. According to UMI, investments in electric-bus corridors or congestion-pricing
measures would be far more effective in reducing vehicle density on crowded city roads. The authors argue
that since private cars contribute disproportionately to congestion and pollution, policies that directly
discourage car usage should be prioritized.
Critics of the report contend that UMI overlooks broader, long-term behavioural effects. They argue that
the expansion of bicycle-sharing networks may gradually reduce car dependency by increasing the visibility
and social acceptance of cycling. Behavioural-economics researchers note that most sustained transportation
shifts begin with small, incremental changes rather than sudden modal switches.
Environmental groups, meanwhile, claim that the report underestimates indirect benefits. A rise in cycling,
they argue, supports the development of safer bike lanes, increases demand for car-free zones, and reduces
noise pollution-all of which contribute to sustainable cities, even if the immediate impact on traffic is
limited. They further assert that public-bicycle systems attract tourists and occasional riders who would
otherwise rely on taxis or ride-sharing services, thereby offering additional environmental gains.
Supporters of UMI respond that such arguments, while valid, do not directly challenge the core claim: that
bicycle-sharing programs alone cannot significantly reduce traffic congestion unless they specifically
target car users. They argue that without a clear reduction in car-based commuting, funds should be directed
toward interventions with proven impact. The debate therefore centers on whether short-term evidence should
outweigh potential long-term behavioural changes when designing mobility policies.
Which of the following is an assumption required for the UMI report’s conclusion?
Options:
- A: Long-term behavioural changes will not significantly reduce car usage.
- B: Most people who start cycling will continue to rely heavily on public transport.
- C: Reducing private-car usage is the most effective way to reduce congestion.
- D: Bicycle-sharing programs have no environmental benefits in the short term.
Solution
-
Step 1: Identify UMI’s conclusion
UMI यह conclude करता है कि bicycle-sharing programs traffic congestion को significantly reduce नहीं करते क्योंकि नए users private cars से shift नहीं हो रहे।
-
Step 2: Determine what must be true for this to hold
यह conclusion तभी logic के साथ टिकता है जब कार-usage कम करना traffic congestion कम करने का सबसे effective तरीका हो।
-
Step 3: Match this with the options
Option C इसी assumption को express करता है।
-
Final Answer:
Reducing private-car usage is the most effective way to reduce congestion. → Option C -
Quick Check:
अगर car usage कम करना जरूरी न होता, तो UMI का conclusion logically follow ही नहीं करता। ✔️
Quick Variations
1. Policy recommendations के पीछे छुपे assumptions पहचानना।
2. Evidence जोड़कर या हटाकर argument को strengthen या weaken करना।
3. Competing viewpoints-researchers vs policymakers, report vs critics-का evaluation करना।
Trick to Always Use
- Step 1 → Conclusion पहले पहचानें।
- Step 2 → Reasoning समझें-लेखक यह conclusion क्यों मानता है?
- Step 3 → खुद से पूछें: “इस reasoning के काम करने के लिए कौन-सी बात सच होना जरूरी है?”
Summary
Summary
- Author का conclusion और उसे support करने वाली reasoning पहचानें।
- देखें कि नई जानकारी argument को strengthen करती है, weaken करती है या irrelevant है।
- Assumption वह missing link है जो argument को logically काम करने देता है।
- Evidence, claim, counterclaim और logical support में फर्क समझें।
याद रखने का example:
“Strengthen support जोड़ता है, Weaken logic तोड़ता है, Assumption argument को पकड़कर रखता है।”
