Exercise 5 - Part 4
You are going to read an article about deaf children developing language. For questions 1–10, choose from the sections of the article (A–E). The sections may be chosen more than once. Choose the best answer for each question.
A Battery-powered cars are currently treated as the primary solution for reducing tailpipe emissions, but the automotive market transitioned far too rapidly without refining complete battery life cycles. Lithium-ion manufacturing relies heavily on intensive chemical extractions that severely damage local aquatic environments and deplete natural resources in developing nations. True innovation requires shifting research budgets toward solid-state battery technology, which increases energy density while eliminating flammable liquid components. Furthermore, forcing electric vehicles into heavy industrial transport is a mistake; long-haul commercial trucking requires a dense energy source that batteries cannot provide due to their immense weight. Consumer passenger cars can benefit from electrification, provided we establish standardized recycling protocols to reclaim valuable raw metals at the end of a vehicle's functional life.
B The current public fixation on individual vehicle battery technology completely ignores the fragile state of regional electrical infrastructure. Charging millions of electric cars simultaneously during peak evening hours will cause widespread power grid failures unless we invest heavily in nuclear and tidal baseload energy. An efficient transition utilizes vehicle-to-grid smart systems, allowing parked cars to feed electricity back into the municipal network during high-demand periods. This cloud-managed synchronization transforms consumer cars into decentralized power banks, balancing supply without upgrading physical transformers. While some environmentalists advocate for hydrogen fuel cells as an alternative, the infrastructure required to compress and transport hydrogen gas safely is economically unfeasible compared to optimizing our existing electrical distribution framework.
C Urban planning departments frequently mistake vehicular electrification for genuine urban sustainability, continuing to design cities around private automobiles rather than human beings. Swapping internal combustion engines for electric motors fails to resolve urban congestion, traffic safety hazards, or suburban sprawl. Municipal budgets should be directed toward high-speed light rail systems and protected micromobility lanes, encouraging citizens to abandon private vehicles entirely. Forcing workers to buy heavy electric cars to commute across sprawling highways is a regressive environmental strategy. Furthermore, the particulate matter generated by tire wear on heavy electric vehicles contributes significantly to microplastic pollution in urban air and waterways. True sustainability is achieved by designing compact, walkable neighborhoods where the necessity for personal automotive travel is eliminated.
D Global automotive policies tend to ignore the immense environmental and humanitarian toll of raw mineral supply chains, focusing exclusively on localized city emission metrics. The extraction of cobalt and nickel for modern electric vehicle batteries often involves exploitative labor practices and severe habitat destruction in post-colonial economies. Automotive companies must invest in alternative chemistry profiles, such as iron-phosphate matrices, which eliminate reliance on scarce minerals despite having slightly lower range capabilities. Additionally, governments must mandate comprehensive supply-chain transparency from source to showroom. Banning specific engine types without providing subsidized public transport alternatives creates deep social inequalities, penalizing low-income commuters who rely on older vehicles for economic mobility.
E While policymakers debate chemical battery variants, the true frontier of zero-emission industrial transport lies in green hydrogen and synthetic e-fuels. For maritime shipping fleets and transcontinental aviation, batteries are an absolute thermodynamic impossibility due to physical scale and weight constraints. Utilizing surplus renewable wind energy to split water molecules produces clean hydrogen, which can then be synthesized into liquid fuels that match existing fueling infrastructure. This approach allows us to utilize trillions of dollars of existing global pipeline and engine infrastructure while transitioning to complete carbon neutrality. The primary hurdle is currently manufacturing efficiency, which requires targeted federal subsidies to scale production to industrial levels. We must avoid a narrow-minded technological monopoly centered exclusively on individual electric passenger cars.
