Answer:
1. Quirrell tells Harry he is the one who tried to kill him.
2. He tells Harry professor Snape was actually trying to save Harry.
3. He tells Harry he is the one who let the troll in during Halloween.
Explanation:
In J. K. Rowling's "Harry Potter and the Philosopher's Stone", the main character Harry Potter is famous in the world of wizards and witches. When he was just a baby, the infamous Lord Voldemort, an evil wizard, tried to kill him, but Harry survived.
Now, Harry is 11 years old and attending his first year at Hogwarts, the magic school. <u>He thinks professor Snape, who clearly hates Harry, is trying to kill him and also trying to obtain the philosopher's stone. To Harry's astonishment, it is professor Quirrell who is doing all that. Quirrell seems shy and weak, but he is serving Lord Voldemort. He casts a spell to try and kill Harry during a Quidditch match, but Snapes casts a countercurse to save him. Quirrell also let a troll into the castle to distract everyone during Halloween while he went searching for the stone but, once again, Snape went after him. Quirrell tells Harry those things while they are in the last chamber, searching for the stone.</u>

Primary Research: Primary research usually means a primary source. For example, Primary Research can be interviewing someone, conducting research. Other examples can be observations, case studies, surveys, experiments etc. The individual directly collects information from the experiment.
Secondary Research relies on secondary sources for example using a book to prepare for a report. Secondary data can be books, articles published, statistical data, reports, and case studies.
So basically, primary research is direct contact to collect the data and secondary is using other sources rather than directly getting the information from the source. Hope this helps.
