Answer: In the first sentence it is said that Kwach learnt one more thing which is teaching while in the second sentence it is said that Kwach was also one of the people who learnt to teach.
Step-by-step explanation:
The sentences in English have different meanings even if they are formed from the same words. The placement of the words in the sentences change the meaning of the sentences. So is the case in the two sentences given here. In the first sentence : Kwach even learnt how to teach, it means that Kwach along with learning other things he also learnt how to teach.
While in the second sentence : Even Kwach learnt how to teach, it means that along with other people, Kwach was also one of them who had learnt how to teach. So this shows that even though the words used in the sentences are the same, still both have different meanings because of the change in the placement of the words.
