To find the reasons, I set up a table at a large building and offered two kinds of chocolates-high-quality and ordinary ones. 2. There was a large sign,"One kind of chocolate per customer." 3. We also set the price of the high-quality chocolates at 15 cents, which was cheaper than the regular price, and the ordinary ones at one cent. 4. Our customers acted with a good deal of rationality: 5. they compared the price and quality of the chocolates and about 73% of them chose the high-quality chocolates and 27% chose the ordinary ones. 6. Next we decided to see how "FREE!" might change the situation, so we offered the high-quality chocolates for 14 cents and the ordinary ones for free. 7. We had only lowered the price of both kinds of chocolate by one cent. 8. However, what a difference "FREE!" made!

マーカー部分の構文を解説して欲しいです。(特にbut周辺) 加えての質問で Laufer vigorously deniedは分詞構文か関係代名詞節(thatの省略)どちらで考えても良いですか？

The case, which involves a small hotel in Maine, could weaken ADA protections and have broader ramifications* for the enforcement of other civil rights laws, legal experts say. It was made somewhat more complicated this summer, when Laufer's former attorney in Maryland hotel lawsuits was disciplined for improper conduct. After a court order, lawyers for the Maine hotel accused Laufer of participating in "unethical extortionate* scheme" - an allegation* Laufer vigorously denies, but (4) one that led in part to her request that the high court dismiss her case.

The turning point suddenly came in December 2004. Dr. Oda received an unexpected call from Thailand after a huge tidal wave had hit its southern region. The government wanted to try his powder to supply the victims with clean water, which led him to Thailand soon afterward. There, his powder helped to create precious, clean water. This successful result attracted global attention to the powder. It was then used in Mexico and Bangladesh. It is currently being used to purify dirty water in about 80 countries in need of drinking water. People are often amazed and shout, "It's a magic powder" when they see brown and cloudy water become clear just before their eyes.

例題 250 3つの数が等差数列 1 等差数列と等比数列 ** 数列 a, b, cはこの順に等差数列で、公差は正である.a+b+c=45, abc=3135 のときa, b, c の値を求めよ. (東京工科大) 考え方 等差数列であるから,この場合,どれかの項と公差がわ かればよい. 等差中項 一般に,等差数列の連続する3つの項は次のようにおく ことができる. (dは公差) b-d b b+d (i) a b c とおく. 26=a+c が成り立つ. +d + d (i) a, a+d, a+2d とおく. (iii) b-d, b, b+d <. 解 この場合は,() のおき方で解くとdが消去できて,計算しやすい. 公差をdとすると, 3つの数は, a=b-d,b,c=b+d とおける.a+b+c=45, abc=3135 であるから, [(b-d) +6+(b+d)=45 ......① \(b−d)·b·(b+d)=3135 |36=45 ①より, 6(62-d2)=3135 6=15 ...... ...2 …...①' ・②' これを②'に代入して, 15(225-d2)=3135 これより, d=±4 d>0より, d=4 したがって、3つの数は, 15-4, 15, 15+4 よって, α=11,6=15,c=19 (別解) a,b,c が等差数列をなすから, 26=a+c ...... ① また, a+b+c=45 ...... ②, abc=3135 ..③ ①,②より, 36 = 45 だから, 6=15 225-d2=209 d2=16 d=±4 ①③より、 atc=30,ac=2091 acは2次方程式 2-30t+209=0 の2つの解であ 2数α,βを解と るから, (t-11) (t-19)=0 より, t=11, 19 る2次方程式 x²-(a+β)x+α =0 公差は正だから, a <c すなわち, a=11, c=19 よって, a=11,6=15,c=19 Focus a,b,c が等差数列 3つの数が等差数列 26=a+c a-d, a, a+d とおく (dは公差)
