Answer

Brief Explanations:

  • "Experimenting" is more precise than "working very hard" as it specifically describes the scientific process they engaged in.
  • "Inexpensive and abundant" is more precise than "cheap and available" as it uses more formal and scientific language.
  • "Participants" is the correct term as it refers to the people involved in the project.

Answer:

experimenting; inexpensive and abundant; Participants
