複選題17. Plant hormones (phytohormones) trigger significant physiological changes at extremely low concentrations. Their mechanism of action typically involves the binding of hormone molecules to specific receptors, which activates internal signal transduction pathways to regulate gene expression or enzymatic activity. Based on current understanding of plant hormone signaling, which of the following statements are correct? (A) Each hormone triggers a single, specific physiological response that remains consistent across all tissues and plant species. (B) The same hormone can produce different physiological outcomes depending on the tissue type, developmental stage, and receptor/signaling context. (C) Hormone action is strictly independent of dosage; the physiological outcome is determined only by the presence or absence of the signal. (D) Physiological outcomes are often the result of complex interactions—such as synergy or antagonism—between multiple hormone classes rather than a single isolated signal. (E) Plant hormones act only locally at the site of synthesis and are incapable of functioning as long-distance systemic signals through vascular tissues.

12.某保險公司分析理賠金額資料,發現少數案件金額極高。業務主管認為這些案件可能是真實重大事故,不一定是錯誤資料。資料分析人員最適當的處置為何?(A)不經確認直接刪除所有高額案件(B)先以統計方法與領域知識判斷是否為錯誤、合理極端值或需特殊處理的案例(C)將所有高額案件金額統一改為平均值(D)只要是離群值,就代表資料蒐集失敗

13.某行銷團隊完成顧客分群前,想先了解年齡分布、消費金額分布、欄位缺失狀況與變數間關聯。此階段最接近資料分析流程中的哪一項工作?(A)探索性資料分析(EDA)(B)模型正式部署(C)資料庫硬體採購(D)API權限開通

14.某能源公司以過去三年每小時用電量建立需求預測模型。工程師打算隨機切分訓練與測試資料,但資料主管提醒此方式可能使未來資料出現在訓練集中。下列哪一項做法最適當?(A)採用時間序列切分,依時間順序以較早資料訓練、較晚資料驗證或測試(B)將所有資料打亂後平均分配到訓練與測試集,以提高樣本均衡(C)只使用最近一天資料訓練模型,以避免資料量過大(D)將測試集結果回填到訓練集,以提高準確率
