Franz was reluctant to go to school because the lesson on participles was not prepared. This is explained in the story "The Last Lesson" by Alphonse Daudet.

Explanation:

• The story is set in a small village in Alsace, which was a part of France but was annexed by Germany in 1871.

• The story revolves around a young boy named Franz who is a student in a French school. The school is about to be closed down as the Germans are taking over the region.

• On the last day of school, the village is filled with soldiers and the school is taken over by a German teacher named Herr Hamel.

• Franz is reluctant to go to school on this day because he had not prepared for the lesson on participles. He expected the teacher to be lenient on this last day of school, but instead, he found out that it was going to be a serious lesson.

• Franz was worried that he would be scolded by Herr Hamel for not preparing for the lesson. He felt embarrassed and ashamed that he had not taken his studies seriously.

• This reluctance to go to school shows that Franz was not a very diligent student and did not take his studies seriously. He was more interested in enjoying the outdoors and watching soldiers drill.

• However, the events that unfold on the last day of school change Franz's perspective on education and the importance of learning. He realizes that the French language and culture are worth preserving, and he regrets not taking his studies seriously.

• The story highlights the importance of education and the impact it can have on an individual's life. It also shows how political and social changes can affect the education system and the lives of students.
