Here are the answers to the objective questions: 1) Why can't keywords be used as variable names in pseudocode? C) Keywords are reserved by the language and have designated purposes. Keywords have specific meanings and functions within a programming language or pseudocode. Using them as variable names would create ambiguity and confuse the interpreter or compiler. 2) If there are errors in the executable code and it needs to be run one step at a time to find the errors, what development tool should be used? D) debugger A debugger is a software tool that allows programmers to execute code step-by-step, set breakpoints, and inspect the state of variables to identify and fix errors (bugs) in a program. 3) What keywords are used to construct if statements? A) if, else, endif In many pseudocode conventions and some programming languages, if, else, and endif (or end if) are used to define conditional blocks. if starts the condition, else provides an alternative path, and endif explicitly closes the conditional structure. 4) What is the output of this program? No output The program initializes x to 10 and y to 12. The if condition (x > y) evaluates to (10 > 12), which is false. Since the condition is false, the Display statement inside the if block is not executed. There is no else block, so nothing is displayed. That's 2 down. 3 left today — send the next one.
