The book is Patrick Hurley’s Concise Introduction to Logic. 13th edition (10-12 edition will be fine).
Read chapter 1.4 Validity, Strength, etc, 1.5 Proving Invalidity, and 1.3 Deduction and Induction.
Then write a short report for each section (like 3-5 sentences each section) about what you don’t understand or struggle with. Example will be attach.
Practice is just the source you can use to write a report. You doesn’t have to answer that.
