Working with JSON, Arrays, and Structs in BigQuery Reviews

There was a typo in one of the bullet points in the STRUCTS section where it says "It's own alias" but since it is being used as a possessive pronoun, there should not be a comma and the correct typing would be "Its own alias". Also, the control+F nor the schema filters were working to find the correct count of structs or arrays in the schema within the lab. Not sure if this was an incognito window issue, something do do with the way Chrome loads the data in the page on a MacBook or something else. Either way, I couldn't seem to find the right numbers without guessing. Even my manual scrolling and counting didn't seem to match what the lab questions expected. And one of the last questions/challenges involved finding the racer with a 23.2 split_time. The solution required me to use UNNEST() but it worked without this. Gemini says that's because the comma implicitly UNNESTS but I don't recall seeing that explanation in the lab. I remember seeing that on implicitly cross joining, but not for unnesting.
