Question

some insects may provide, some insects are better left untouched. when trying to identify whether or not an insect is harmful, one must pay attention to several important characteristics: color, smell, and sound.

insects using camouflage to avoid detection from people and predators. warning coloration is also an effective defensive mechanism. red, yellow, orange, and especially black are warning signs to stay away. the bright yellow colors of bees, their painful, stinging abilities. likewise, the black and orange colors of monarch butterflies, in contrast to the foliage that is green and in which they inhabit, issue warnings to potential predators. birds that foolishly prey on monarch butterflies will find themselves very ill from the toxins that monarch butterflies contain.

some insects produce offensive smells and unique sounds to repel people and predators invading their space. skunks emit odors that can be smelled several inches, linger for significant lengths of time, and smell similar to those produced by skunks. bombardier beetles expel clouds of foul-smelling chemicals that are fatal to other insects and can cause slight burns to humans. madagascar cockroaches hiss when disturbed or alarmed, while crickets and flies are audible. even to humans are made by mosquitoes and certain beetles. recognizing insects defense mechanisms, which vary in magnitude and differ from species to species, helps people identify which insects are beneficial to humans and best avoided.

which change, if any, is needed to the underlined text?
while rasping sounds that are audible even to humans are made by the wings of garden tiger moths

options:

• while rasping sounds are made by the wings of garden tiger moths that are audible even to humans
• while rasping sounds audible even to humans are made by the wings of garden tiger moths
• while garden tiger moths make rasping sounds with their wings that are audible even to humans
• no change.

Explanation:

To solve this, we analyze the original sentence and the options. The original is "while rasping sounds that are audible even to humans are made by the wings of garden tiger moths". We need to check which option rephrases it correctly. Option 2 ("while rasping sounds audible even to humans that are made by the wings of garden tiger moths") has incorrect word order, making the meaning unclear. Option 3 ("while garden tiger moths make rasping sounds with their wings that are audible even to humans") changes the structure but keeps the meaning? Wait, no, let's re - examine. Wait, the original structure is about the sounds being made by the wings and audible to humans. Wait, maybe I made a mistake. Wait, the correct option should preserve the meaning. Wait, the original sentence: "while rasping sounds that are audible even to humans are made by the wings of garden tiger moths". Let's parse each option:

Option 1: "while rasping sounds are made by the wings of garden tiger moths that are audible even to humans" – this makes it seem like the moths (not the sounds) are audible, which is wrong.

Option 2: "while rasping sounds audible even to humans that are made by the wings of garden tiger moths" – this is a jumbled structure, the "that are made..." is misplaced.

Option 3: "while garden tiger moths make rasping sounds with their wings that are audible even to humans" – this correctly conveys that the moths make sounds with their wings, and those sounds are audible to humans. Wait, but the original says the sounds are made by the wings. But maybe in terms of rephrasing for clarity, option 3 is better? Wait, no, maybe I messed up. Wait, the original underlined text is "while rasping sounds that are audible even to humans are made by the wings of garden tiger moths". Let's check the options again. Wait, the user's options:

1. while rasping sounds are made by the wings of garden tiger moths that are audible even to humans

1. while rasping sounds audible even to humans that are made by the wings of garden tiger moths

1. while garden tiger moths make rasping sounds with their wings that are audible even to humans

Wait, the correct option should have the sounds being audible to humans and made by the wings. Option 3 says the moths make sounds with their wings (so the wings are the source) and the sounds are audible to humans. This is a correct rephrasing. Wait, but the original says "sounds... are made by the wings", option 3 says "moths make sounds with their wings" – which is equivalent in meaning (the wings are the instrument the moths use to make the sounds). So option 3 is correct. Wait, but maybe I made a mistake. Alternatively, maybe the correct option is 3. Wait, let's check the grammar. The original has a passive construction, option 3 is active but preserves the meaning. So the correct option is the third one: "while garden tiger moths make rasping sounds with their wings that are audible even to humans".

Answer:

1. while garden tiger moths make rasping sounds with their wings that are audible even to humans
