Transcript:

Water authorities sample the numbers and species of midges present in a water course above and below a discharge – for example from a sewage treatment plant – to monitor contamination of the water by organic matter. Oil, and detergents used to disperse oil, also alter the character of the surface layer – and will have a negative effect on species such as meniscus midge larvae that depend on this delicately balanced habitat. Some insects have economic and medical importance. For example, there's a huge body of literature devoted to mosquitoes. Anything that bites and transmits disease is likely to attract research funding. A Scandinavian team showed that midge bites could lead to a mild fever but - its effects were short lived and quickly alleviated.

Option 4: "its effects were short lived and quickly alleviated"

Explanation: This option accurately reflects the text's statement about the effects of midge bites, which are described as mild and quickly alleviated. It aligns perfectly with the context provided, confirming the transient nature of the effects.

Option 1: "some insects are more important"

Explanation: This option suggests a general statement about the importance of some insects, but the text specifically discusses the effects of midge bites rather than comparing the importance of different insects. Therefore, it does not align with the context provided.

Option 2: "sewage treatment is more important"

Explanation: This option implies a comparison of importance regarding sewage treatment, which is not supported by the text. The text focuses on the effects of midges and their habitat rather than prioritizing sewage treatment.

Option 3: "its effects were highly negative"

Explanation: While the text mentions negative effects on species due to contamination, it specifically states that the effects of midge bites are mild and short-lived. Thus, this option misrepresents the severity of the effects described.
