They also have an 25 flavor and a higher percentage of solids.
答案：(B) intense
語意「它們（儲存洋蔥）風味也更強烈」，intense（強烈的）符合，呼應後文適合辛辣料理；anxious（焦慮的）、organic（有機的）、effective（有效的）都不合。
intense 在你腦中大概綁在情緒或壓力上（intense pressure、an intense person），很少想到它可以拿來形容味道。答對率只有 44%，超過一半的人失手，最多人挑 organic——講到食材就想到「有機」，而且 organic onions 確實是有這種說法。
先看空格所在的結構：an ______ flavor and a higher percentage of solids。and 把兩件事並列，後面那件用的是比較級 higher，明顯是在和新鮮洋蔥比。既然是並列，前面那件也應該是「比新鮮洋蔥更…」的某種性質。再回頭找對照：前面說新鮮洋蔥 sweeter and milder tasting（更甜、更溫和）。既然兩種洋蔥處處相對，儲藏洋蔥的味道就該是更濃烈。往下一句還有第三道保險：storage onions are the best choice for spicy dishes that require longer cooking times or more flavor（適合需要久煮或口味更重的辛辣料理）。more flavor 直接對應 intense flavor。intense 的核心意思是「程度很強的」，用在情緒是「強烈的」，用在味道、顏色、光線就是「濃烈的」（劍橋詞典）。
anxious：焦慮的，形容人的情緒，不能形容味道。organic：有機的，講的是栽種方式，與味道的濃淡無關，也對不上前後的對比。effective：有效的，用來說某個方法管用，味道談不上有效不有效。
an intense flavor（濃烈的風味）、intense pressure（極大的壓力）、intense heat（酷熱）、a higher percentage of（較高比例的…）、spicy dishes（辛辣的料理）、require longer cooking times（需要較長的烹煮時間）。
Onions can be divided into two categories: fresh onions and storage onions. Fresh onions are available 21 yellow, red and white throughout their season, March through August. They can be 22 by their thin, light-colored skin. Because they have a higher water content, they are typically sweeter and milder tasting than storage onions. This higher water content also makes 23 easier for them to bruise. With its delicate taste, the fresh onion is an ideal choice for salads and other lightly-cooked dishes.
Storage onions, on the other hand, are available August through April. 24 fresh onions, they have multiple layers of thick, dark, papery skin. They also have an 25 flavor and a higher percentage of solids. For these reasons, storage onions are the best choice for spicy dishes that require longer cooking times or more flavor.
