Application of the ladder of abstraction in TOK

My grand father claims that the fruits on his trees are ripening earlier and earlier he thinks it is due to global warming.

Knowledge claim : that fruits are ripening faster due to global warming.

Concept: Experience , sense perception , history, memory,science, truth.

Poor knowledge question:Do we need experience to prove that fruits are growing faster ?

Intermediate knowledge question: Can science justify why fruits are growing faster?

Good knowledge question: to what extent can we use memory to achieve the hi storical truth?
