Question

Read the passage.

The emerald ash borer beetle is one of the top five most invasive species in North America, and its spread should be monitored carefully. It is native to Asia, and researchers believe that it was imported to North America on a piece of wood or wood product. The adult female beetle lays its eggs on the ash tree’s bark. The larvae bore into the tree after they hatch, hence the insect’s name, and feed on the tree’s tissues. Infestation is almost always fatal for the tree. Since the early 2000s, when the beetle first arrived in North America, tens of millions of ash trees have died. This has devastated the ecosystem, since many insects and birds rely on ash trees for their diet. It has also changed the landscape of many cities, as infected trees have had to be removed.

Which idea does the speaker emphasize by using cause/effect in this passage?

Emerald ash borer beetles are an invasive species.
The transportation of wood increases the risk of invasive species.
The destruction of ash trees has had negative consequences.
Emerald ash borer beetles need to be destroyed to save the ash trees.

Answer 1

Emerald ash borer beetles need to be destroyed to save the ash trees.

Invasive species like the emerald ash borer beetle can have a major impact on ecosystems and can displace native species, disrupt food chains, and cause economic damage. It is therefore important to monitor and control their spread to protect both natural and human environments.
