Answer:

No

Step-by-step explanation:

External validity refers to being able to apply the results of the research experiment to real life situations. Therefore based on the information provided in the question it can be said that Dr. Rajah's experiment does not have external validity. This is mainly due to the fact that brain teasers are problems that does not reflect on real world problems or events.
