Yukimura and the others will be giving presentations at the summer study sessions. There's less than a month left until the training camp, but Kosuke still hasn't picked a research theme.

Instead of showing off how smart you are, 
explain it so people can understand!
!بدل التفاخر بمدى ذكائك، اشرح ذلك حتى يفهمه الناس

¡En vez de presumir lo listos que son,

En vez de presumir lo listos que sois,
¿por qué no lo explicáis?
Expliquez simplement,
au lieu de vous la péter !
Invece di far vedere a tutti quanto siete intelligenti,
spiegate le cose per farle capire alle gente!
Pare de ostentar sua inteligência e
fale de um jeito que todos entendam!
Не выпендривайтесь своим умом, 
а понятно объясните!
