Answer:
Pilot study 
Explanation:
A pilot study is a preliminary study (prior to the actual study) done in a smaller scale to determine if the main components of the actual study (duration, cost, adverse events) will be feasible. 
A pilot study is crucial to determine whether the study is doable and the areas that can be improved before the actual full-scale study takes place. 
In this example, Clara conducted a trial run with a <u>small number of participants</u> to see if the instructions are clear and the experimental setting is plausible. Clara did this <u>before the actual study</u> and she did this trial run in a smaller scale, <u>her goal was to determine if the experimental setting was plausible and areas of improvement</u> (like the instructions), thus, this meets the requirements of a pilot study.
