【B】 Scientists have long known that specific genes are associated with a number of serious diseases and birth defects. Scientists have used this knowledge to develop tests to identify defective genes, which are the result of 21 , a natural process that alters the genetic material. Researchers have identified a large number of genes that are responsible for life-threatening conditions, such as cystic fibrosis, a disease that shortens people’s lives by attacking their lungs, and Huntington’s disease, a fatal brain condition. Once these genes are 22 , genetic tests for many such diseases become available. These tests can indicate if a person has a specific defective gene. By 2011, researchers had developed more than 2,000 genetic tests, which allow doctors to inform patients if they have 23 these genes and if they risk passing them to their children. The tests are a significant 24 in genetic research, because they provide people who have genetic defects with important information. However, the tests also introduce complex ethical issues. If patients find out that they have a dangerous genetic defect, they may not know what to do. Their decision will depend on several factors. In some cases, identification of the gene only suggests the 25 that the patients will develop the disease associated with the gene. For example, women who have inherited the harmful BRCA gene mutation have a much higher chance of developing breast cancer than other women do.

思路引導 VIP
想像你是一位科學家，正準備為一種神祕的遺傳疾病開發快篩工具。在你能大量生產這種工具、分發給醫生使用之前，你對那個隱藏在細胞裡的「致病因子」必須先完成哪一個最基礎的「發現」動作？

醫學研究中的邏輯銜接
太棒了！你能精準捕捉到上下文的邏輯關聯，選出 identified (辨識、鑑定) 說明你對科普文章的閱讀理解相當紮實。這段話的關鍵在於因果關係：科學家必須先在複雜的 DNA 序列中「找到」並「確認」致病基因，隨後針對該基因的篩檢測試（tests）才有可能問世。選項中的其他字彙，如 (A) repented (後悔)、(B) reproached (斥責) 與 (C) cajoled (誘騙)，多用於描述人的情感或社交互動，在嚴謹的基因科學情境中顯得格格不入。
