Practice Listening: Multiple Choice, Single Answer ID: #34831 Short Insects and Streetlights
Instructions ›
Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

There's growing alarm over plunging insect populations with climate change, habitat destruction and pesticides all thought to play a role. But now, scientists say there's another culprit: artificial streetlights. Researchers from the charity Butterfly Conservation counted caterpillars at the sides of brightly lit roads. Compared with similar stretches of unlit roads, caterpillar numbers were reduced by half, suggesting streetlights can affect the abundance of insects - at least on a local scale. The scientists say with insects in trouble, we should be doing all we can to reduce negative influences. But there are practical solutions such as dimming streetlights in the early hours, installing motion sensors, or using color filters to modify the light.

According to the speaker, what is the result of the research into insect population near streetlights?

Option 3: "Insect population drops 50% near streetlights."

Explanation: This option accurately reflects the findings of the research. The text states that caterpillar numbers were reduced by half when compared to unlit roads, indicating a 50% drop in insect population near streetlights.

Option 1: "The number of insects doubles near the streetlights."

Explanation: This option contradicts the findings presented in the text. The research indicates that caterpillar numbers were reduced by half near streetlights, not that they doubled. Therefore, this statement is inaccurate.

Option 2: "Most insects are killed by the strong lights."

Explanation: While the text discusses the negative impact of streetlights on insect populations, it does not state that 'most insects are killed.' The research specifically mentions a 50% reduction in caterpillar numbers, which does not equate to a majority being killed.

Option 4: "Insects are in trouble if they fly near streetlights."

Explanation: This option implies a general danger to insects flying near streetlights but does not specify the quantitative impact. The text focuses on the specific finding of a 50% reduction in caterpillar numbers, making this statement too vague and not directly supported by the research.
