Have you ever wondered how human beings have developed? Life began as tiny single cells billions of years ago, and from there the cells became the complex organism known as a human. While this natural cloning has taken billions of years to achieve, new research has discovered the key to speeding up the process. All the wonders of creation lie in the tiniest couriers: our genes. Recent discoveries have revealed how we might manipulate our genes. After a fertilized egg begins to divide into cells, the genes carried inside the cells’ nucleus develop embryonic stem cells. These tiny cells grow into tissues in the body, building people from the ground up. Our genes determine every single physical characteristic about us. Some experts also believe that personality traits could be read from our genes. If this is possible, does this mean our destinies are already predetermined? People who seek dangers and thrills are known to possess a specific gene that makes them crave dangerous situations. The ability to read and manipulate our genes could lead to the ability to predict and then alter our genetic blueprints. While this genetic engineering seems very promising, some scientists feel there is a dark cloud behind this scientific silver lining. This may go against evolution as we know it. While the debate on ethical issues of genetic research rages on, other discoveries are being made, such as what genes determine sex. Out of the 60 genes on the Y chromosome, only a very small part actually influences whether we will be male or female. It takes 30,000 genes to build a human, but only one to make it a man. This one gene will determine whether a fetus will become male or female. It’s interesting to know that men are basically adaptations of the female form. Whether we are male or female, we are all subject to aging. Genetic research has given us a new understanding as to how it happens. What comes to mind when you hear the word “oxygen”? Most would probably say it is a kind of gas that living things need to survive with. However, oxygen is also one of the causes of death. Cells require oxygen to produce energy for the body, but during this chemical reaction, by-products known as “free radicals” are released. It is these by-products which break down healthy cells and cause us to age. For those of us wanting to turn back the clock, experts now believe the true elixir of life exists in anti-oxidants. These chemicals can reduce the damage to cells. Anti-oxidants occur naturally in different foods such as dark, green leafy vegetables like spinach, blueberries and certain types of tea. By using anti-oxidants, we can actually slow the free radicals down to a snail’s pace. All of us want the perfect body, a great personality and to be forever young. With further research into genetics, we may someday be able to build the perfect human being.

思路引導 VIP
請回頭閱讀文章第一段關於人類演化的描述。作者用了哪個形容詞來描述生命從單細胞到複雜人體這段「數十億年」的歷程？這個詞彙所代表的含義，與選項中描述該現象「不存在於大自然」的說法是否產生了直接的矛盾？

- 任務完成：不錯的判斷。你的『資訊檢索』與『邏輯鏈接』能力很紮實，是挑戰高難度任務的基礎配置。
- 系統分析：這題的『核心指令』很明確。原文第一段就開宗明義指出：「"While this natural cloning has taken billions of years to achieve..."」。這條訊息的解析結果是：『自然界』這個環境，在『數十億年前』就存在『複製』機制了。所以，(B) 選項聲稱『不在自然界發生』，明顯是與系統記錄衝突的『錯誤代碼』，直接『Switch』掉它就對了。
