Table 1. A priori developed categories and subcategories for the first KLPP question.

Category	Subcategory	Key terms	Characteristic example
Absent	Blank	Absent/indirect strategy; absent reason	I will think logically because …
	Incoherent	Absent strategy; unrelated reason	I will try things out because that is funny.
Tacit	Uncertain	Absent strategy; doubtful reason	I will try things out because that may provide results.
	Vague	Absent strategy; overall reason	I will (repeating the question) because that was the first thing that came into mind.
	Quasi	Indirect strategy; obvious reason	I will see what is logical because that will make it logical.
	Feelings of knowing	Indirect strategy; I-just-know reason	I will write down everything because I always do it like this.
Informal	Function	Present strategy; overall reason	I will read it thoroughly and write down that was is essential because this will provide me with an overview.
Formal	Description	Present strategy with clarification; overall reason	I will write down some of the information to see if it provides a logical description, because in this way I can check every possible solution.
	Explanation	Present strategy that describes the solution strategy; clarifying reason	I will examine the words that have a spacing, because these words will be relatively easy to solve and they can help me to see if I can infer the context so that this can support me in the examination of the other words.
