Which of the following is not an example of a closed-context prompt?

Select one:
a. Write a haiku about a cat.
b. Calculate the area of a triangle with base 5 cm and height 8 cm.
c. Summarize the plot of the novel “Around the World in 80 Days.”
d. How many planets are in our solar system?


Answer

a. Write a haiku about a cat


Explanation (each option)

a. Correct.
“Write a haiku about a cat” is an open-context prompt because it does not have a single factual or deterministic answer. The response depends on the model’s creativity, choice of words, and style. Different outputs are all equally valid, making it an open-ended creative task.

b. Incorrect.
“Calculate the area of a triangle with base 5 cm and height 8 cm” is a closed-context prompt because it has a single correct factual answer (½ × base × height = 20 cm²). There is no room for creativity; the model must provide a specific result.

c. Incorrect.
“Summarize the plot of the novel ‘Around the World in 80 Days’” is also a closed-context prompt. The novel’s plot is fixed and does not change, so the summary is bounded by a specific source of information. While summaries can vary in length or style, the underlying facts are constrained.

d. Incorrect.
“How many planets are in our solar system?” is a closed-context prompt because the correct answer is 8. It is a fact-based question with only one valid answer
