🎯 What you'll practice: A fresh academic-style passage with True/False/Not Given questions.
Battery costs for electric vehicles have fallen by more than 80% over the past decade, driven largely by improvements in manufacturing scale rather than any single scientific breakthrough. However, some analysts caution that further large cost reductions may be harder to achieve, since the raw materials used — particularly lithium and cobalt — remain subject to volatile global prices. Despite this, most manufacturers continue to project falling battery costs through the rest of the decade, betting that recycling programmes and alternative chemistries will offset material price pressure.
1-B 2-B 3-C 4-B | 5 = 80 6 = cobalt 7 = NOT GIVEN — the passage never says any manufacturer has abandoned cobalt 8 = recycling programmes and alternative chemistries 9 = TRUE — directly stated | 10 = "Some analysts" only confirms that a subset of analysts hold this cautious view — it says nothing about the opinions of all other experts, so it cannot be used to support a universal claim like "no experts believe" the opposite; the passage explicitly notes elsewhere that "most manufacturers" still project falling costs, which would directly contradict such a claim anyway.
