Answer:
A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}
Explanation:
Since <em>python does not use type when declaring a variable</em>, you must make sure you make your variables correctly or else it won't compile correctly. Lists use braces[]; Strings use quotes, "" or ''; Integers are just declared with a number(s); Dictionaries use brackets{} and inside are <u>attributes of something</u>. For instance, you can use dictionaries to describe ages, {'"Bryan": 6, "Alex": 13, etc.} <u>Sort of like a json file</u>. Dictionaries also tend to use <u>uppercase letters</u> when describing something. The only answer that has all the attributes correct is A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}
hope i helped :D

<em>SQL Query</em>
///////////////////////////////////////////////////////////////////////////////////////////////////
select Genre_Name, Number_Purchased from Genre
INNER JOIN Tracks on Genre.Genre_Name = Tracks.Genre_Name
WHERE Number_Purchased >= 10 AND Tracks.price >= 1
ORDER BY Number_Purchased ASC;
Explanation:
First off, I selected the required columns from <em>Genre</em> Table.
Then I inner joined <em>Genre</em> table with <em>Tracks</em> table, to get the <em>price</em> of tracks of the corresponding Genres.
Then the required Where conditions are written, which includes one from the <em>Tracks</em> table.
Finally, the Order by statement is written by <em>Number_Purchased</em> column in ascending (ASC) order.
