Correct Transcript:

The research involved marine snails, but probably applies to all snails, which may expend a third of all their energy producing mucus. So an obvious benefit is that individual snails can save energy that would otherwise go into cutting fresh trails. Snail experts had thought this was the case, but the new study proves it. And it wasn’t easy - the researchers actually measured the fitness of snail trails. A new trail could accommodate a second traveler without additional mucus. But whether trails got thicker, as snails added a bit of mucus where necessary.

Printed "replies", the speaker says "applies"

Explanation: Listen for "probably applies to all". On the page it reads "replies", and they start with different letters, so listen to the whole word.

Printed "rails", the speaker says "snails"

Explanation: You will hear "individual snails can". You see "rails" printed, and they start with different letters, so focus on the first sound.

Printed "grating", the speaker says "cutting"

Explanation: On the recording the words are "cutting fresh trails". It appears as "grating" on the page, and both end the same, so listen to the beginning.

Printed "weakness", the speaker says "fitness"

Explanation: Listen again to "measured the fitness of". That page shows "weakness", and they start with different letters, so hear the start carefully.

Printed "first", the speaker says "second"

Explanation: In the audio you hear "accommodate a second traveler". Printed there is "first", and the words end differently and one is longer, so trust the audio.

Printed "tethered", the speaker says "whether"

Explanation: Here the speaker says "But whether trails got". The printed word starts with a different letter and ends differently, so listen to the whole word.

Printed "graded", the speaker says "added"

Explanation: The speaker says "added a bit of", not "graded". The page shows "graded", and they end the same, so focus on the start to tell them apart.

"mucus" matches the audio

Explanation: "producing mucus. So an obvious" may look odd because mucus is a technical word. It is spoken exactly as printed, so do not click it.

"researchers" matches the audio

Explanation: "the researchers actually measured the" has a long word that can look tricky. The speaker says it exactly as printed, so do not click it.
