premise: Each of five experts—a lawyer, a naturalist, an oceanographer, a physicist, and a statistician—individually gives exactly one presentation at a conference. The five presentations are given consecutively. Each presentation is in exactly one of the four following languages: French, Hindi, Japanese, or Mandarin. Each expert speaks exactly one of the languages. The following conditions must hold: Exactly two of the presentations are in the same language as each other. The statistician gives the second presentation in Hindi. The lawyer gives the fourth presentation in either Mandarin or French. The oceanographer presents in either French or Japanese; the same is true of the physicist. The first presentation and the last presentation are in Japanese. Suppose the condition that the statistician gives the second presentation in Hindi is replaced with the condition that the statistician gives either of the presentations given in Japanese. If all the other original conditions remain in effect, which one of the following could be the order, from first to last, in which the experts present?
hypothesis: the statistician, the oceanographer, the naturalist, the lawyer, the physicist
