Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35.

Australia is suffering from one of its worst fire seasons in history, with more than two dozen people killed, thousands of homes destroyed, and millions of acres burned so far. Unfortunately, fires like this, exacerbated by the effects of climate change, will likely rage again, but Australia’s government can take steps to minimize their destruction.

With warming temperatures, Australia will face longer fire seasons. To reduce future damage, governments at all levels must act. Areas of focus should include enhancing early warning systems and fire prediction capabilities; launching public awareness campaigns on the dangers posed by climate-fueled bushfires and necessary prevention measures; conducting more controlled burns; and developing more stringent building codes that address climate risk.

At the state and local levels, communities need to professionalize their firefighting capabilities. They should invest in improved training that educates firefighters and local leaders about the changing characteristics of bushfires. And, once this fire season subsides, states should oversee how and where rebuilding occurs, including restricting redevelopment of particularly fire-prone areas.
