my answer - "It is easy to travel by train." It is very correct because the first meaning of " rahisi" is ( especially as adjective ) - easy, simple.
The second position has - cheap
I agree. The only thing wrong with your answer is that we do not say "by the train" in English - it's just "by train". (by train/car/boat/plane/air ... on foot ... all without an article)
Thank you and strait ahead I will correct this. :)
I wish it was either cheap or easy to travel by train in the UK, sadly it's neither... Maybe I need to try trains in East Africa!
