Answer:
Deductive
Step-by-step explanation:
This is the process of reasoning from one or more statements, when a person wants to reach to a logically certain conclusion.
In the question it says that the participants were presented with two statements and a conclusion statement and they had to answer if the conclusion matched with the two statements.
You can infer that it is deductive reasoning because the experiment wants to reveal if the people can deduct if the conclusion statement makes sense after reading the other two statements.
