Question

butterflies affects all insects by vicky stein for my 11th birthday, i received a perfect, weird, road - trip amusement: a book filled with pictures and descriptions to help kids decode the splatters of insects that smacked into the front of a moving vehicle. whether that sounds like macabre fun or makes you grumble about keeping the windshield clean, a steep decline in reported bug splatters in recent years should actually make us worried, entomologists and ecologists say. in a new study published tuesday in plos one, a group of researchers analyzed one of the rare data sets that tracks butterfly abundance, taken from 21 years of volunteer surveys in ohio. they found an average population decline of 2 percent per year, which means that over the course of the study, ohio lost more than a third of its butterfly population. some species of butterflies showed no change in abundance. however, and a few others actually became more common.
ot everything is going to decline in exactly the same way,\ said corrie moreau, an entomologist and evolutionary biologist from cornell university who was not involved in the new research. \but we are seeing in this study and others what main claim does the author make in the passage? (1 point) butterfly populations are declining. people dislike having to clean their windshields. a study about butterflies was recently published. some butterfly populations are stable.

Explanation:

The passage starts by introducing a book about insect splatters on wind - shields and then mentions a study showing a decline in butterfly populations in Ohio. While some species are stable or more common, the overall trend and the concern expressed by entomologists and ecologists highlight the decline as the main claim.

Answer:

Butterfly populations are declining.
