How do you lose weight in the first place?—Mostly, through breathing. While the concept of “burning” fat is not altogether wrong, losing fat involves plenty of carbon dioxide leaving your body. As the Washington Post explains: Researchers found that to burn a pound of fat, a human needs to inhale about three pounds of oxygen and drink about a pound of water. Water can exit the body in plenty of ways—poop, pee, sweat, saliva and any number of bodily fluids—but your lungs handle the brunt of the weight loss.\nYour fat “goes” into the atmosphere. (And no, it doesn’t contribute to global warming.) When it does go, you’re also releasing the extra storage of vitamins and toxins along with it. That might not sound like a good thing, but in the long run it’s far better to be rid of them. As Popular Science states, a kind of pesticides, among other pollutants, are known to get bound up in fat—they leak into our food supply: Bodies don’t seem to store enough of these to become toxic, but the constant build-up leaves you vulnerable to exposure. And they do start to re-emerge when you lose weight.\nBy losing weight at a healthy pace (1-2 pounds a week), the limited number of pollutants released will not overload your bloodstream. Your urine will make quick work of them. Extreme dieting is a different story. The more weight you lose, the more of these toxins enter your bloodstream.\nSince we no longer face the same problem as our ancestors—most of us don’t have to worry about whether or not we’ll eat tonight, or tomorrow—fat storage plays a different role in our bodies than previously. Many avoidable health problems are due to this excessive storage of energy, hormones and toxins. Some researchers claim 70 percent of our medical problems can be addressed through a healthier lifestyle, which includes eating better and moving more.

請仔細閱讀文章第二段，尋找關於「污染物（pollutants）」如何進入我們身體的描述。作者在提到這些物質會跟脂肪結合時，特別舉出了一個具體的化學物質名稱作為例子，那個單字是什麼呢？

太棒了！你非常精確地從繁雜的資訊中提取出了關鍵細節。這題考驗的是對文章中具體實例的定位與對應能力。你能選出 (C) Pesticides（殺蟲劑），代表你在閱讀時不僅能理解大意，還能敏銳地捕捉到作者用來支持論點的具體證言。
文本證據與細節辨析
在文章第二段中，作者探討了脂肪流失時會釋放儲存物，並明確提到：「一種殺蟲劑（a kind of pesticides）與其他污染物，已知會與脂肪結合」。這裡的 Pesticides 正是文中提到的「pollutants」或「toxins」的具體例證。雖然脂肪（Fat）在體內扮演了儲存這些物質的角色，但它本身是能量與物質的「載體」，而非「毒素」本身。
