To simplify this quiz, you should only care about the invalid cases explicitly mentioned by the hints. 2. To make sure you are using the correct original data file, please download the Lab 4 data “covid.db” again before you start answering the questions. The data file is in lab_4_setup.zip, click this link (lab_4_setup.zip) to download it directly. DO NOT leave this quiz to download it from other pages, since you can only attempt once for this quiz. For all the following questions, you need to make up the SQL queries, run them in SQLite over the "covid.db", and select the correct choice.
