By changing the type of obstacle the characters face
What’s the options? Can u ask more clearly
Skills? I wouldn't say skills, but you think about what you red and write, you use what you know from your brain to basically understand words in a book or even when you write them down, etc. If this doesn't help, look up all the skills of reading and writing on google =)
A) First Option
Reason: I did Process Of Elimination. The last definition talking about London, is not it, the one before the last one talks about a charge made for goods, which is also not it. Also, a bundle made for transportation, that's not money, that's like Carrots being sent to the store. So, to me, it has to be the first option.
