Read the following passage about Christmas trees and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.
[I] The environmental impact of Christmas trees goes beyond choosing real or artificial. [II] Real trees, typically spruce, fir, or pine, are grown on plantations for about ten years, supporting biodiversity by providing habitats for farmland birds and insects. [III] These trees play a small but meaningful role in preserving rural landscapes and preventing alternative, less sustainable land uses, like urban development. [IV].
Artificial trees, while reusable, have a significantly higher carbon footprint during production and transport. According to the Carbon Trust, they must be reused for several years to match the lower carbon footprint of real trees.
Disposal methods are critical. Real trees release their stored carbon upon decay, but if they end up in landfill, anaerobic conditions produce methane, a far more potent greenhouse gas. Composting, chipping, or using trees for energy or habitat restoration are far better alternatives. Additionally, some companies now offer tree rentals, and pot-grown trees can be replanted, making them excellent sustainable options.
Sustainability efforts can also include buying locally grown trees, reducing travel emissions, and supporting certified sustainable farms. While Christmas trees represent a minor part of land use and the global carbon cycle, their management highlights opportunities for improvement. Reducing waste, eliminating fertilisers, and avoiding landfill disposal are practical steps toward making this cherished tradition more eco-friendly.
Though a small element of the festive season, Christmas trees remind us of the broader need to balance ecological responsibility with tradition. With mindful practices, this holiday symbol can contribute positively to both biodiversity and climate goals.

(AI giải đề cho tôi)
Trong đoạn 3, 'potent' mô tả khí methane là một khí nhà kính có tác động mạnh hơn nhiều ('a far more potent greenhouse gas'). 'Potent' nghĩa là mạnh, hiệu lực cao, đồng nghĩa với 'powerful'. Các phương án khác (natural, typical, widespread) không phù hợp ngữ cảnh. Đáp án trùng với key nguồn (câu 24 = B).
