In many cities, the songs of a common songbird, the great tit, carry a higher pitch than the songs of the same species in nearby woodlands. Dr. Elena Rocha proposes that the birds raise their pitch to keep their songs from being masked by the low-frequency rumble of urban traffic and machinery, which covers low notes far more than high ones. If she is right, the higher pitch is not a fixed trait of city birds but a flexible response that tracks the noise around them.

Which finding, if true, would most directly support Rocha's hypothesis?

ACity birds hatched and raised in a quiet aviary still sang at the same high pitch as wild city birds.

BCity birds consistently sang at higher pitches than woodland birds across every month of the year.

CCity great tits tend to build their nests closer to the ground than woodland great tits do. The same city birds also tend to raise their broods a little earlier in the season, differences that set city and woodland populations apart in ways that have nothing to do with the pitch of their songs.

DWhen traffic noise dropped during a citywide quiet period, individual city birds were recorded singing at lower pitches than they had during the noisy daytime hours.
