Correct Transcript:

Protons are finally transferred to the LHC both in a clockwise and an anticlockwise direction, where they are accelerated for 20 minutes to 6.5 TeV. Beams circulate for many hours inside the LHC beam pipes under normal operating conditions. For each collision, the physicist's goal is to count, track, and characterize all the different particles. The charge of the particle, for instance, is obvious since particles with positive electric charge bend one way and those with negative charge bend the opposite way. Also, the momentum of the particle can be determined. Large Hadron Collider (LHC) is the world's largest particle accelerator lies in a eternal. The LHC is a ring roughly 28km around that accelerates protons almost to the speed of light before colliding them head-on. Protons are particles found in the atomic nucleus.
AI explanationShows the answer. Tap to open.
Printed "transmitted", the speaker says "transferred"

Explanation: On the recording the words are "transferred to the LHC". Both words start with t, so listen to the whole word.

Printed "aiming", the speaker says "under"

Explanation: Listen again to "inside the LHC beam pipes under". The printed word starts with a different letter, so the start of the sound will help.

Printed "placements", the speaker says "particles"

Explanation: In the audio you hear "all the different particles". The first letter is the same, so wait for the rest of the word to decide.

Printed "effort", the speaker says "charge"

Explanation: Here the speaker says "negative charge bend". The two words start with different letters, so listen from the first sound.

Printed "cannot", the speaker says "can"

Explanation: The speaker says "can be determined", not "cannot". The spoken word is much shorter, so listen for a short word.

Printed "passage", the speaker says "eternal"

Explanation: Listen for "lies in a eternal". The printed word starts with a different letter, so the first sound will be different.

Printed "life", the speaker says "light"

Explanation: You will hear "speed of light before". Both words start with l, so hear the full word to tell them apart.

"LHC" matches the audio

Explanation: "The LHC is a ring roughly" may look like a tricky name. It is spoken exactly as printed, so do not click it.

"Protons" matches the audio

Explanation: "Protons are particles found" looks like a repeat, so you might doubt it. The speaker says this word exactly, so do not click it.
