Exercise 5 - Part 3
You are going to read an article about the same topic with various authors' perspectives. Then you are given 10 statements, decide which author (A to D) fits the best with each statement. Choose the best answer for each question.
A: Arthur (The Automotive Engineer)
Battery-powered cars are currently the most efficient solution for reducing tailpipe emissions, but the automotive market transitioned far too rapidly without refining battery life cycles. Lithium-ion manufacturing relies heavily on intensive chemical extractions that severely damage local aquatic environments in developing countries. True innovation requires shifting research 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 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: Beatrice (The Energy Grid Specialist)
The current public fixation on vehicle battery technology completely ignores the fragile state of our 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. This decentralized approach turns automobiles into mobile storage units, stabilizing power distribution far better than standard layouts. While some express deep concern regarding battery mineral mining, traditional fossil fuel extraction remains exponentially more damaging to global ecosystems. The primary hurdle is grid capacity, not localized factory supply chains.
C: Charles (The Urban Transport Advocate)
Replacing millions of gas-powered private cars with millions of electric private cars is a completely short-sighted strategy that completely fails to address urban congestion or traffic safety. A battery-powered traffic jam is still a traffic jam that degrades city livability. True metropolitan sustainability is achieved by reallocating road lanes exclusively to high-speed electric bus rapid transit systems and protected bicycle lanes. Furthermore, the massive weight of heavy electric SUVs accelerates asphalt deterioration and creates lethal hazards for pedestrians. Municipal funding should be stripped from private vehicle charging subsidies and redirected toward expanding affordable public rail networks. We must design cities for human beings to walk safely, rather than catering to expensive private alternative vehicles.
D: David (The Environmental Economist)
Market incentives and carbon pricing mechanisms are the only realistic drivers of a successful green transportation transition. Governments should implement severe fossil fuel taxes while offering generous tax credits to companies developing hydrogen fuel cell technologies for heavy commercial shipping and long-haul logistics. Regarding passenger cars, private charging infrastructure must be expanded rapidly through public-private partnerships to boost consumer adoption rates. While urban planners romanticize a world reliant entirely on public trains and bicycles, private vehicle ownership remains an absolute logistical necessity for millions of rural and suburban families. A practical, market-driven compromise combines electrified private transport for remote areas with robust public transit investments inside high-density city centers.
