Does "кот" refer to cat in general (regardless of gender)? Because I know that кошка works as well for cat.
Кот refers specifically to male cats. It should have been translated as "tomcat" here as it has been everywhere else in the course (that I've seen)
Привет, Русский. This is in English. Это В Английский. I love Sonic the Hedgehog. Я люблю Ёж Соник. Russia is in Europe and Asia. Россия в Европа и Азия. This planet, Earth, is good! Это планета, Земля, Хорошо! Red is good. Красний Хорошо. Bye y'all.
Every sentence you wrote was incorrect in some way, except «привет, русский» but the word русский is not normally capitalised, so I guess that sentence wasn't completely correct either.
So could you kindly provided corrections so we all know what it should be instead? Спасибо. :-)
