Answer 1

Here are the answers to your questions:

**Question 1:** Which of the following is an advantage of the waterfall methodology?
- **The project is easily managed because it is only in one phase at a time.** (This response highlights that the waterfall methodology's structured approach allows for clear management and oversight of each individual phase of a project.)

**Question 2:** A car can have a state of "on" or "off". A human has many states, such as "hungry," "tired," "happy," "angry," "content," and so forth. The focus of these states would best fit which programming paradigm?
- **Object-oriented** (This response is correct because the concept of states attributes aligns well with objects in object-oriented programming, where objects can have various states and behaviors.)

**Question 3:** Which of the following statements is false?
- **An operating system is a type of application software.** (This response is false because an operating system is classified as system software, while application software refers to programs designed to carry out a specific task, like Microsoft PowerPoint or an antivirus program.)
