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.

Q: Answer-The growing concern over climate change has led to global efforts to electrify the transportation se...

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.

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.

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.

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.

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.

E None of these
