Correct Transcript:

Comparisons of different animals have shown that larger brains provide greater intelligence, but they also guzzle more energy and have other consequences. Now scientists have observed the effects of varying brain size within a single species: guppies. The work is in Current Biology. Swedish researchers bred two different lines of guppies, selecting one for larger brains and one for smaller. The fish quickly modified until brains were nine percent larger in the big-brained line than in the other. Not surprisingly, when 48 guppies were given learning tests, large-brained female fish outperformed small-brained females. However, males from both lines scored about the same, possibly because the female guppies' visual system was more suited to the type of intelligence test used. But big brains also had a downside—the brainier fish had smaller guts, by 20 percent for males and 8 percent for females.
AI explanationShows the answer. Tap to open.
Printed "involved", the speaker says "observed"

Explanation: Listen for "observed the effects". The printed and spoken words start with different letters, so listen to the word start.

Printed "celebrate", the speaker says "big brained"

Explanation: You will hear "big brained line than". The printed and spoken words start with different letters, so listen to the start.

Printed "situate", the speaker says "large brained"

Explanation: On the recording the words are "large brained female". The spoken phrase is much longer, so listen for a longer phrase.

Printed "passerby", the speaker says "possibly"

Explanation: Listen again to "possibly because the". Both words start with p, so wait for the middle of the word.

Printed "prerequisites", the speaker says "intelligence"

Explanation: In the audio you hear "intelligence test used". The printed word makes no sense before "test", so listen for the correct start.

"Current" matches the audio

Explanation: "The work is in Current Biology." The name looks formal. The speaker says it exactly, so do not click it.

"guzzle" matches the audio

Explanation: "they also guzzle more energy" has a strong action word and may seem wrong. The speaker says it exactly, so do not click it.
