Fitzgerald wanted his novel to be mysterious. He need not give out all the information because he wanted the readers to be suspenseful regarding the story. Gatsby doesn't understand how he isn't welcome because he's too naive for thinking he is important.
Answer:
A. Observational study
Explanation:
An observational study measures the characteristics of a population by studying individuals in a sample, but does not attempt to manipulate or influence the variables of interest.
A designed experiment applies a treatment to individuals (referred to as experimental units or subjects) and attempts to isolate the effects of the treatment on a response variable.
Hence, we can see that proposed study is observational.
