Accompanist / Piano Instructoryuri
Accompanist pianist × piano instructor × web writer. I began piano lessons at age four and, inspired by my piano teacher, decided to pursue music. I went on to specialized music programs in high school and university, where I discovered the appeal of accompanying instrumentalists and singers. Currently, alongside teaching piano, I work mainly in my home region of Aichi as an accompanist for flute, voice, choir, and more. Through lessons, my students often introduce me to trending songs, and my hobby is trying anything on the piano—Japanese and Western pop, commercial jingles, and beyond. Since 2021, I’ve also been active as a web writer, covering music and a variety of other genres.

[Logic Quiz] Flexible Thinking and Creativity Are the Key! A Comprehensive Showcase From Classics to Brain Busters (11–20)

There are two types of people: “good” people who always tell the truth and “bad” people who always lie. Person A says, “B and C are the same type.” When someone asked C, “Are A and B the same type?”, what would C have answered?

See the answer

A and B are the same type.

If A is a good person, then B and C are also good, and the honest C would answer, “A and B are the same type.” If B and C were bad, C would lie and would likewise answer, “A and B are the same type.” On the other hand, if A were bad, then B and C would be different types; if C were good, A and B would both be bad. If C were bad, A and B would be different types, but C would answer that they are the same. In other words, regardless of who each of the three is, C’s answer will be, “A and B are the same type.”
