      Question

      The growing concern over climate change has led to

      global efforts to electrify the transportation sector. In parallel, cost of Li-ion (Lithium-ion) battery technology has decreased by a staggering order of magnitude in the past decade. The convergence of these two factors has resulted in a unique time in our history where we are at the cusp of a dramatic transition in the transportation sector, with electric vehicles poised to replace petrol vehicles. Directions : In the following question, a small passage is given. The options below have 4 sentences. From these, choose the sentence as your answer, that best describes the passage briefly, without the addition of any other information. If no sentence serves as the summary of the given passage, choose option 5, ‘None of these’ as your answer.
      A Two major factors have led to the transition of the transportation sector, from petrol vehicles to electric vehicles; concerns about climate change and the affordable cost of Li-ion battery technology. Correct Answer Incorrect Answer
      B Although there are global efforts to switch from petrol vehicles to electric vehicles, the cost of Li-ion battery still poses a challenge, and people around the globe are finding a possible way to make cost-effective batteries, thus paving way for a less-damaging future. Correct Answer Incorrect Answer
      C Vehicles have been a severe threat to climate change, and the idea that the transition to electric vehicles might be a solution to the problem is paving way for global efforts to invent advanced technologies that would decrease the cost of Li-ion batteries. Correct Answer Incorrect Answer
      D The concerns over climate change and the cost of Li-ion battery technology are the two factors that prevent us from transitioning to electric vehicles, and history proves that electric vehicles are causing indirect damage to the environment. Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Only option 1 summarises the paragraph. Option 2 and 3- The cost of Li-ion batteries has been decreasing. So, there is no need to find a new way to reduce the cost. Option 4- These are the two factors that are driving us for the transition, not preventing us.
