In the question given below, a paragraph is given with options (a), (b), (c), (d) and (e). Read the paragraph carefully and identify which of the given options correctly explains the paragraph or correctly summarises it. Can you teach an old society a new trick? Habits of over-consumption that push our excessive carbon emissions run deep. They are locked into our subsidised, car-biased transport system, our cheap-flights holiday culture and the numbing complexity that confronts us if we want to give our homes a green makeover. More fundamentally, we live in a culture that defines us first and foremost as material 'consumers.' We've become locked in as carbon emitters on three sides: surrounded by physical, economic, and cultural infrastructure that gives most individuals precious little carbon room for manoeuvre.

Let us examine the given options one by one: Option (a): This focuses on technology as a future solution, which is not the highlight of the passage. The emphasis is on the difficulty of changing current habits. Option (b): This option accurately reflects the main theme of the paragraph, which highlights the difficulty of changing societal habits and infrastructure that contribute to high carbon emissions. It recognizes the complexity of the issue and the challenges involved in addressing it. Option (c): While consumerist culture is mentioned in the paragraph, it also highlights other factors such as physical and economic infrastructure. Option (d): This option acknowledges the complexity of overhauling infrastructure to be more carbon-neutral, which is mentioned in the paragraph. However, it focuses primarily on infrastructure rather than the broader societal habits and cultural norms discussed in the paragraph. Option (e): This presents the opposite perspective. The passage focuses on the challenges of changing ingrained habits, not a widespread shift towards sustainability. Hence, the correct answer is option (b).
