Answer 1

Let's go through the questions one by one.

Question 1: Which of the following is false?

1. A heap is generally faster than a stack. (False) - This statement is generally false. Stacks are usually faster than heaps because allocation and deallocation in a stack is simpler and more efficient, following a last-in, first-out (LIFO) principle.
2. A stack uses a last in, first out (LIFO) approach. (True) - This statement is true. A stack indeed follows the LIFO principle.
3. A heap must be manually managed. (True) - This statement is true. In many programming languages (like C/C++), heap memory management (allocation and deallocation) is done manually by the programmer.
4. A stack automatically deallocates space when variables are no longer needed. (True) - This statement is true. The stack automatically deallocates space for variables when they go out of scope.

So, the false statement is: "A heap is generally faster than a stack."

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.

• False - In Python, you must explicitly close a file you have opened, unless you use a context manager (with statement), which automatically closes the file for you when the block is exited, whether normally or by exception.

Question 3: What type of file is best for storing discrete items that are stored in rows?

• CSV - CSV (Comma-Separated Values) is best suited for storing discrete items in a tabular format, where each row represents a record.

To summarize:

1. False
2. False
3. CSV
