Final answer:
To write a research paper, you would use Application software (option D). Software developers work in the Tertiary sector of an economy, providing services such as software development. Writing processes, including for research papers, may suggest a linear order but can vary in actual application.
Step-by-step explanation:
If you need to write a research paper, the category of software you would use directly is D) Application. Application software is a program or group of programs designed for end-users to perform specific tasks like word processing, creating spreadsheets, making presentations, conducting research, and more. A common example of application software for writing a research paper is a word processing program like Microsoft Word or G Docs.
Regarding the sector of an economy where a software developer would be working, the correct answer is c. Tertiary. The tertiary sector is involved in providing services rather than goods, and software development falls under this category. As services become more specialized, some roles including those of software developers may also be considered as part of the Quaternary sector, which is an extension of the tertiary sector involving knowledge-based services like information technology and research and development.
The process for writing does not strictly follow a linear progression but can involve moving back and forth between different stages. Nonetheless, the categories described in a writing process may suggest an ideal sequential order: starting with the development of a hypothesis, conducting an observational study or a controlled experiment, making observations, and finally, compiling the findings into a research paper.
Hence, the answer is option D.
