How many rivers are there in europe? надо ли артикль the тут ставить?

Здесь артикль не ставится

Нет, не надо ставить здесь артикля. 

thank you very much for your nice christmas card. you asked me to write about my family. our family is a typical russian family: a father, a mother, two children and a cat. we are an intelligent family and we get on well with each other.

my mum is a science teacher. she is sociable. her hobby is painting. my dad is a computer programmer. he is close. he has a good sense of humour. my little sister ann is funny and sometimes naughty.

My family consists of five people: mum, dad, my brother, grandmother and me. my brother's name is nikita. my mother's name is irina. my dad's name is oleg. my grandmother's name is valentina. we live very friendly. ( можно начать: my family is not very big. there are 5 of us: mum, dad, my brother, grandmother and me. my brother's name is nikita. my mother's  name is irina. my dad's name is oleg. my grandmother's name is valentina.)
