At the start of a cross-subject（语境补充词）/cross-subject/ challenge, Mina's team received a real case rather than a textbook（教科书）/'tekstbuk/ exercise. The opening evidence connected garlic（大蒜）/'gɑ:lik/, gather（集合、聚集）/'gæðә/, gender（性）/'dʒendә/, generous（慷慨的、有雅量的）/'dʒenәrәs/, genius（天才、天赋）/'dʒi:njәs/, gentle（温和的、文雅的）/'dʒentl/, genuine（真正的、真实的）/'dʒenjuin/, gifted（有天才的）/'giftid/, globe（球、球状物）/glәub/, goat（山羊）/goʊt/, golf（高尔夫球）/gɒlf/, goods（商品）/gʊdz/, grab（抓握、掠夺）/græb/, and gradually（逐渐地）/'grædʒuәli/. The links looked unusual, but each detail came from a witness, label, form, or measurement（尺寸、度量）/'meʒәdmәnt/ in the case file. The team has already reviewed the complete plan.

A second folder added grain（谷粒、颗粒）/grein/, gramme（克）/gramme/, grand（庄重的、壮观的）/grænd/, grasp（抓住、紧握）/græsp/, grateful（感谢的、感激的）/'greitful/, gravity（地心引力、重力）/'græviti/, greedy（贪婪的、贪得的）/'gri:di/, greenhouse（温室）/'gri:nhaus/, greet（问候、致敬）/gri:t/, grocery（食品杂货店、食品杂货业）/'grәusәri/, guilty（犯罪的、有过失的）/'gilti/, guy（家伙；男子）/gaɪ/, gym（体育馆）/dʒɪm/, and gymnastics（体操、体育）/dʒim'næstiks/. Some entries described people and places; others recorded objects, actions, or changing conditions. The students sorted each clue by time and source instead of forcing an early answer. The final choice was explained to everyone at the meeting.

The hardest set included ham（火腿）/hæm/, handkerchief（手帕、头巾）/'hæŋkәtʃif/, handwriting（笔迹）/ˈhænˌdraɪtɪŋ/, harm（伤害、损害）/hɑ:m/, harmony（协调、和睦）/'hɑ:mәni/, harvest（收获、成果）/'hɑ:vist/, hatch（孵化、舱口）/hætʃ/, hence（因此、从此）/hens/, herb（药草、香草）/hә:b/, hesitate（犹豫、迟疑）/'heziteit/, hike（徒步旅行、远足）/haik/, honey（蜂蜜、甜蜜）/'hʌni/, honour（荣幸；荣誉）/ˈɒnə/, and horrible（可怕的、遭透的）/'hɒrәbl/. Mina checked spelling and context while a partner marked facts that could be tested. Mina, who led（lead的过去式和过去分词）/led/ the discussion（讨论）/dɪˈskʌʃn/, asked for clear evidence. Then the supervisor（管理者、监督者）/.sju:pә'vaizә/ said, “Do not hide an awkward clue merely because it weakens（削弱、减弱）/'wi:kәn/ your first idea.”

The last working board brought together host（主人、旅馆老板）/hәust/, hug（紧抱、拥抱）/hʌg/, humble（使...卑下、降低...地位）/'hʌmbl/, hunt（狩猎、追捕）/hʌnt/, hurricane（飓风、暴风）/'hә:rikәn/, hydrogen（氢）/'haidrәdʒәn/, ideal（理想、典范）/ai'diәl/, identical（同一的、恒等的）/ai'dentikәl/, idiom（习语、成语）/'idiәm/, ignore（不理睬、忽视）/ig'nɒ:/, illegal（违法的、不合规定的）/i'li:gәl/, immediately（立即）/ˌɪˈmiˌdiətli/, imply（暗示、意味）/im'plai/, and import（进口货、进口）/im'pɒ:t/. The group compared the four boards, removed repeated claims, and wrote（写下）/roʊt/ a short reason beside every decision（决定）/dɪˈsɪʒn/. If the first method fails, we can try another one. That rule helped them correct two mistakes without blaming a teammate（队友）/'ti:mmeit/.

They planned to check in（办理登记手续）/ʧɛk ɪn/, check out（办理退房；结账离开）/ʧɛk aʊt/, and set off（出发）/sɛt ɔf/ at safe times. Nobody would go on board（在交通工具上）/ɔn bɔrd/ without checking the notice in advance（提前）/ɪn ədˈvæns/. In case of（万一；如果发生）/ɪn keɪs əv/ trouble, one adult would be responsible for（对……负责）/bi riˈspɑnsəbəl fər/ contact while the student could apply for（申请）/əˈplaɪ fər/ official help. The completed record told（告诉）/toʊld/ a clearer story than the first draft. It did not pretend that every clue was equally important; it showed how disciplined reading, calm cooperation（合作、协力）/kәu.ɒpә'reiʃәn/, and a checkable（语境补充词）/checkable/ decision could turn a crowded case into useful（有用的）/ˈjuːsfəl/ action.
