Correct Transcript:

Stem cells are the body's master cells, the raw material from which we are built. Unlike normal body cells, they can reproduce an indefinite number of times and, when manipulated in the right way, can turn themselves into any type of cell in the body. The most versatile stem cells are those found in the embryo at just a few days old. This ball of a few dozen stem cells eventually goes on to form everything that makes up a person.
In 1998, James Thompson announced that he had isolated human embryonic stem cells in the laboratory. At last, these powerful cells were within the grasp of scientists to experiment with, understand, and develop into fixes for the things that go wrong.

Printed "rare", the speaker says "raw"

Explanation: Here the speaker says "the raw material from". The printed word "rare" is on the page but not in the audio. Both words start with r, so listen to the whole word.

Printed "sort", the speaker says "type"

Explanation: The speaker says "any type of cell" not "sort". The printed word "sort" is on the page but not in the audio. They start with different letters, so listen from the first sound.

Printed "human", the speaker says "person"

Explanation: Listen for "makes up a person". You see "human" on the page, but you hear a different word. They start with different letters, so follow the whole spoken word.

Printed "pronounced", the speaker says "announced"

Explanation: You will hear "James Thompson announced that". Printed here is "pronounced", yet the audio uses another word. Both words end with the same letters, so listen to the start.

Printed "grip", the speaker says "grasp"

Explanation: On the recording the words are "within the grasp of". The page shows "grip", however the speaker says a longer word. Both start with g, so listen for the longer spoken word.

"embryo" matches the audio

Explanation: "found in the embryo at" is the phrase in the text. Embryo sounds technical, but the speaker says it exactly. Do not click it.

"isolated" matches the audio

Explanation: "he had isolated human" appears in the printed text. Isolated may look odd, but the speaker says it exactly. Do not click it.
