all right just four more questions then we're done with this beast which gives

00:07

the strongest evidence for the answer to that previous question to do that [text on screen]

00:11

previous thing here so we're gonna scroll back previous question which

00:14

choice best take the relationship between bird densities and noise levels

00:16

so we're trying to find a support for the effects of anthropogenic noise so [text on screen]

00:22

we're cruising down here and we're gonna just go look for lines 44 through 46 and

00:28

we find and it's it's out you conduct in the nether one kinda 80% of little bird

00:30

species child reduce numbers near relatives about a next thing is not the

00:33

study though suggestive did not isolate noise from other possible complicating [text on screen]

00:36

factors but renovation corridors or delusions in collusion okay that's

00:39

supportive you know really nice to go and write howling studio and what are

00:41

these effects excited over a mile in the forest wanted the noise the lake with

00:42

popular leader were confirmed these effect and contributed a significant

00:45

finding birds with high-frequency call it looks like look remember that lower

00:47

frequency okay that's right support it's gotta be d the

00:50

connection between low-frequency traffic noise and bird calls is drawn explicitly [heavily trafficked highway]

00:55

in the first sentence of paragraph six right there it explains that birds with [text on screen]

00:59

low-frequency calls had their calls masked or interfered with well the first

01:04

example explains bird reductions but it doesn't say why they occur so get rid of [writing on blackboard]

01:08

a the second shows that factors other than noise are in play but it fails to

01:12

connect bird density with noise so get rid of E and the third example explains

01:16

that noise and bird calls are linked but well it fails to explain a cause so get

01:20

rid of C so yeah it's D later [bird flies away]
