Which decomposition completes the presentation task?

A student must prepare a five-slide presentation using three supplied articles. The slides must answer two given questions and name at least one supporting article for each answer. The student must submit the finished slides as one PDF file by 16:00 on Friday. Here, the PDF is an exported copy of the slides.

A decomposition divides the task into smaller parts. The result of one part may supply information needed for a later part. Which plan gives connected parts that produce and submit the required final result?

  1. Extract relevant facts and article names; draft both answers with their sources; create and check the five slides from those drafts; export the checked slides as one PDF and submit it by the deadline.
  2. Extract relevant facts and article names; create five slides with empty answer sections; draft both answers in a separate file; export the unchanged slides as one PDF and submit it by the deadline.
  3. Extract the three article titles and author names; draft a summary of those titles and authors; create and check five slides containing that summary; export the slides as one PDF and submit it by the deadline.
  4. Extract relevant facts and article names; draft both answers with their sources; create five slides and export one PDF; correct missing content in the slides and submit the earlier PDF by the deadline.
