この文の下から8行目のstream jumping とはどういう訳し方が正解ですか?

B You are reading the following article as you are interested in studying overseas. Summer in Britain Chiaki Suzuki November 2022 This year, I spent two weeks studying English. I chose to stay in a beautiful city, called Punton, and had a wonderful time there. There were many things to do, which was exciting. I was never bored. It can get expensive, but I liked getting student discounts when I showed my student card. Also, I liked window-shopping and using the local library I ate a variety of food from around the world, too, as there were many people from different cultural backgrounds living there. Most of the friends I made were from my English school, so I did not practice speaking English with the locals as much as I had expected. On the other hand, I came to have friends from many different countries/ Lastly, I took public transport/which I found convenient and easy to use as it came frequently. If I had stayed in the countryside, however, I would have seen a different side of life in Britain. My friend who stayed there had a lovely,/relaxing experience. She said farmers sell their produce directly. Also, there are local theatres bands, art and craft shows restaurants, and some unusual activities like stream-jumping. However, getting around is not as easy, so it's harder to keep busy. You need to walk some distance to catch buses or trains, which do not come as often. In fact, she had to keep a copy of the timetables. If I had been in the countryside, I probably would have walked around and chatted with the local people. I had a rich cultural experience and I want to go back to Britain. However, next time I want to connect more with British people and eat more traditional British food.

問6のl=1のところが理解できません なぜ0にはならないのですか?

62023年度 数学 第4問 (100点) 2つのレポートの異なる度合い (非類似度)を数値化することは, レポートの独創性を の単語の集合をU={W,W2,...,W9} とする。 レポートAに, Uに属する単語が含まれる 評価するために重要である。 レポートのテーマに関する異なる9個の単語を選び,それら と表す。 同様に、レポートB についても調べたところ, 単語の集合 B が A∩B={ws}, かどうかを調べたところ, W2, W3, W's が含まれていた。 このとき, 単語の集合Aを A={w2,W3,Ws} AUB = {W1, W4,Wg} を満たしたとする。 次の問いに答えよ。 ANB 問1 集合 B を求めよ。 問2 集合Aの部分集合をすべて求めよ。 問3 集合ひの部分集合の個数を求めよ。 140*3 & ROTER) ( 問4 集合ひの部分集合X,Y について,集合 z=(XP)(1) の要素の個数n(Z) , n(X), n(Y), n() を用いて表せ。 ここで,Uの部分集合 X,Y に対して、XとYの非類似度d(X,Y) を次の式で定義する。 ((x)(x))) > n(A)th(B) - 2n (AMB) d(X,Y)= n(XUY) →n(A)+(B)-n(AB) 問5 集合 A, B に対して, AとBの非類似度d(A,B) を計算せよ。 NAKON ENCH 18-0 (0) E E-f(xgol)x= (22 E25023 問6 C,DをUの部分集合とする。 n(C)=4, n(D)=6のとき,CとDの非類似度 d(C,D) がとりうる値の最大値と最小値を求めよ。
