Answer: N.B The question seems incomplete and I believe the complete question should be what type of reasoning is this. The answer is abductive reasoning
Explanation: Abductive reasoning is a form of logical inference which starts with an observation or set of observations and then seeks to find the simplest and most likely explanation for the observations.
From the above question, the first premise of the individual observed that hunger leads to tiredness. The second premise of the individual observed that tiredness leads to sleepiness. The individual conclusion then states that hunger leads to sleepiness from all the observation gathered. Note that there could be other reasons why the individual feels sleepy, hence why this type of reasoning is abductive.
