Correct Transcript:

Animals that live in cold climates tend to have stubby limbs—shorter arms and legs—even smaller ears and tails. Picture a penguin and you’ll see what I mean, Biologists have long assumed that these stumpy appendages are an evolutionary adaptation. Shorter extremities minimize heat loss, so animals that are more compact are better suited to the cold. But scientists from Ohio say that temperature may have a more direct effect on the length of an animal's limbs. Because they find that turning up the heat helps cartilage grow—results that were published in the Proceedings of the National Academy of Sciences. The researchers raised mice at several different temperatures, and they confirmed that those kept at a balmy 80 degrees were longer limbed than those who lived at a more chill 45. But how does a little heat make mice more leggy? The answer, they find, lies in the cartilage.

Printed "proprietress", the speaker says "climates"

Explanation: You will hear "in cold climates". The two words start with different letters, so listen to the whole word.

Printed "urologists", the speaker says "Biologists"

Explanation: On the recording the words are "Biologists have long assumed". They start with different letters, and both end with the same letters, so check the whole word.

Printed "infinities", the speaker says "extremities"

Explanation: Listen again to "Shorter extremities minimize heat". The two words start with different letters. They also end with the same letters, so follow the sound.

Printed "consequent", the speaker says "cartilage"

Explanation: In the audio you hear "helps cartilage grow". Both words start with the same letter, so listen to the whole word. The printed word does not make sense before "grow", so trust the audio.

Printed "planned", the speaker says "confirmed"

Explanation: Here the speaker says "they confirmed that those". The spoken word is longer, so listen for the extra sounds in the middle.

"penguin" matches the audio

Explanation: "Picture a penguin and you'll see" may look like a trick because the animal is rare in tests. The speaker says it exactly as printed, so do not click it.

"Proceedings" matches the audio

Explanation: "published in the Proceedings of the" has a formal title that looks odd on the page. It matches the audio exactly, so do not click it.
