low-concentration

男子ゴルフのマスターズ・トーナメントがオーガスタ・ナショナルＧＣで始まりました。石川選手が予選で落ちたり（直後に婚約を発表！）、松山選手が予選を突破したり、タイガーウッズがそれまでの復調がウソのように不調だったりと、何かと話題を提供していますが、CNNが着目したのは、とあるギャラリー。なんと彼の愛犬が一生に一度の宝物と言われる観戦チケットを食べてしまったのでした。最終的には、low-concentration hydrogen peroxide solutionを犬に飲ませて、チケットを吐き出させるという荒技にうったえました。low-concentrationはアメリカでは小学校のサイエンスあたりではじめて出会う表現です。「低い集中」というのは物質の濃度が低いということ。したがって「低濃度の」という意味になります。hydrogen peroxide solutionは過酸化水溶液でしょうか。
「犬が宿題を食べる」という英語世界共通の宿題逃れの言い訳を彷彿させるこの話題、英語圏では受けたでしょうね。はてさて、この方は無事にマスター観戦はできたのでしょうか。詳細は記事にまかせます。（UG）

(CNN) -- As Russ Berkman understood it, desperate times call for desperate measures.
And when your Swiss mountain dog gobbles up your Masters tickets, that means getting out the hydrogen peroxide and getting ready to sift through your canine's vomit.
That's the choice the Seattle resident made after a fit of panic when he realized Saturday night that his beloved canine Sierra had eaten his and his friends' four passes to the prestigious Augusta, Georgia, golf tournament.
Augusta beyond that exclusive golf club
"Laying on the hardwood floor was just the strings from (the tickets)" as he came in from a short trip outside, Berkman recalled. "I knew."

With just a few hours to go before he boarded his 6 a.m. Sunday flight east, he called his girlfriend, who recommended he give Sierra some low-concentration hydrogen peroxide solution, which many recognize as a safe way to get a dog to vomit.
Thankfully, it was late in the day and Sierra hadn't eaten much recently. So when she threw up, the result was "not as bad as you'd think," Berkman said on Thursday.
Still, the tickets were far from whole and far from pristine. Berkman was able to cobble together the tickets into something resembling the four passes he'd received after the annual Masters ticket lottery in August.
So Berkman took off, holding the stitched together passes close to the vest. He also kept from his three buddies the news that his dog had eaten their perhaps once-in-a-lifetime chance to traverse the greens of Augusta National Golf Club.
