Hi Agnieszka. Almost right: 9,834,456 is nine million, eight hundred AND thirty three thousand, four hundred and fifty six. The difference between dinner and supper is a tricky one. In Britain, dinner can be the noon or evening meal, but supper can only be the evening meal. Supper is generally a more formal term, although a formal meal with friends in someone's home rather than restaurant is called a dinner party!

The answer is "surprisedly". But in spoken language we would probably say "in surprise". "Surprisingly" is not a manner of doing something. It is used to say that some information is surprising. E.g. "That article was surprisingly interesting". "He is surprisingly tall". Or "Surprisingly, he has never been to London".

Hi Emperor哈里. In terms of meaning, there is no difference between 'about' and 'or so'. Both work well for saying how many minutes/hours/days, but I think when you talk about specific times (5 o'clock, 1999, the 10th of January), though, 'or so' sounds a bit strange. You should just use 'about' or 'around' to be safe for these kinds of expression of time. By the way "We have to leave about in five minutes" should be "We have to leave in about five minutes". Hope that helps. Neil

I am British and would agree that they have the same pronunciation in most forms of British English. I think some Scottish people would would pronounce the 'r' though.

My opinion is: "I find it difficult" is more common than "it seems difficult", although the meaning is slightly different. Something might seem difficult without you having tried it, but if you find something difficult, it means you have tried it. And "I find it beautiful" is more common than "it's beautiful in my mind".

Hi snarling_wolfy. I don't think you can use 'decent' as the antonym for 'indecent' in this context. I think 'acceptable' or 'appropriate' would be better. I think any other preposition used in place of 'in' might make it ambiguous. If behaviour is acceptable 'for' someone, it means it is acceptable 'to' them i.e. it is acceptable in their opinion.

Hi Jordana. This is a really tough question. You're right that it's generally best to avoid using 'elders' except in the usages you mentioned ["Respect your elders", "the village elders" or as an adjective (My elder brother)]. In this sentence, we could use "the elders' tradition" if we are referring to a community which has 'elders', meaning 'village elders' - a group of old people in a small(ish) community who have power or influence. But it wouldn't be appropriate in a modern society, like you say. ""A clash between older people's' tradition and young people's acculturation" would be more appropriate. I have been thinking hard about "The clash between the elderly's tradition and the young's acculturation" or "The clash between the old's tradition and the young's acculturation?". I think these are fine grammatically but just sound odd to me. I think we would probably say "The clash between the tradition(s) of the elderly and the acculturation of the young" or "or "The clash between the tradition(s) of the old and the acculturation of the young". This is probably due to the use of "the" before elderly and "old" but I couldn't say for sure. Probably a very obscure usage rule. Language is complicated!

Hi! The first part of the sentence is fine, but the second part doesn't make a lot of sense. I would guess you mean "Operation Car Wash is causing quite a stir in Brazil and to some extent around the world", or "Operation Car Wash is causing quite a stir in Brazil and is having some impact on the world".
