Let's go through each question. **Question 1: Which of the following is false?** 1. A stack uses a last in, first out (LIFO) approach (True) 2. A heap must be manually managed. (True) 3. A stack automatically deallocates space when variables are no longer needed. (True) 4. A heap is generally faster than a stack. (False) **Answer:** A heap is generally faster than a stack. (This statement is false; generally, the stack is faster than the heap due to how they manage memory.) --- **Question 2: True or False? In Python, a file is always automatically closed for you after you are done reading it or writing to it.** The answer is **False**. In Python, files are not automatically closed; you need to close them explicitly or use a `with` statement to ensure they are closed automatically at the end of the block. **Answer:** False --- **Question 3: What type of file is best for storing discrete items that are stored in rows?** The most suitable option for storing discrete items in rows is a CSV (Comma-Separated Values) file, as it is designed for tabular data where each row is a separate entry. **Answer:** CSV --- **Question 4: Which of the following is the correct way to instantiate an object belonging to the user-defined class Dog that has attributes of name and breed?** The correct way to instantiate an object in Python is to directly call the class name followed by the arguments needed in parentheses. The option `pet = Dog("Spot", "Dalmatian")` follows this syntax correctly. **Answer:** pet = Dog("Spot", "Dalmatian") --- Summary of Answers: 1. A heap is generally faster than a stack. (False) 2. False 3. CSV 4. pet = Dog("Spot", "Dalmatian")
