Choose the correct letter, A, B or C. The subjects in questionnaire are

(Iris=I Hunter=H)
I:   So, tell me about your research project, Hunter.
H: I created a questionnaire for the study to determine people’s opinions of the relative feasibility of earning a living in Brisbane.
I:   Oh, cool How is it scored? Are they all multiple-choice questions?
H: Well, the questions consist primarily of yesho responses. There are two free-response questions at the end. Participants will use a computer to fill in their answers; that way is really easy to analyse the data afterwards.
I: Great! It sounds like you have a pretty solid idea of what you should do. Just don’t forget to submit a copy of your plans to Professor Curran by the 15th.
H: Ah, I almost forgot!
I: Hmm, you don’t do it for a high grade or praise, but he can review your work and give you feedback.
H: Right, that will be helpful. He has been conducting studies like this for 30 years now.
I: Yep. Oh, and I’m curious — are you going to be in the room giving subjects directions for the questionnaire?
H: Well, I think the instructions will be provided by another representative, who will not be analysing the data. I want them to feel they can answer and be completely anonymous so I will not be in the room. Anonymity is really important for this study.
I: I agree. Good idea. You should tell the representative to remind subjects to fully consider both sides of each issue. Sometimes it’s really easy to immediately check ’yes’ or ’no’ without stopping to think about it completely.
H: That’s so true! It’s like a race to finish the questionnaire first or something. I’ll make sure to include that in the instructions. This report has to be perfect!
I:   Wow, what’s the big deal? I know it’s part of your grade and all...
H: Well, it’s that, but also a well-executed study could grab the attention of faculty in the department, which would be a huge deal.
I:   So... for attention?
H: No, silly! I mean I could really gain the respect of professors who may later take me on as a graduate student in their labs.
I:   Oh, I see.
