More than 35,000 people die each year in the US alone from antimicrobial resistant infections. With novel treatments in short supply, scientists plan to boost available therapies to target antimicrobial resistance. In a paper published in PNAS, researchers used the power of light to give antibiotics a fighting chance. Light interacts with chemicals called photosensitizers to produce toxic reactive oxygen species. Unlike many antibiotics, photosensitizers can sneak past bacterial defenses. For example, it was found that light, plus the photosensitizer curcumin, a chemical found in turmeric, potentiated antibiotic efficacy. In their new study, Dr. Bagnato and his team found that they needed to expose drug-resistant strains of Staphylococcus aureus to high doses of different antibiotics to curb its growth. However, when Bagnato added the curcumin and shone light on the bacteria, a lower dose sufficed. Still, the effects were limited. For most strains, the effects were temporary; the team observed a recurrence in resistance after only a few cycles of bacterial growth. Bagnato emphasized the need for alternative therapies. “Infection does not need one type of weapon; it needs a whole arsenal,” said Bagnato.

請觀察文章最後一段中，博士將『治療方法』比喻成了什麼樣的工具？當他說我們不能只依賴『一種武器 (one type of weapon)』，而是需要一整個『軍火庫 (arsenal)』時，他在強調的是治療手段的『數量多寡』，還是『種類的豐富程度』呢？

脈絡中的隱喻轉化
太棒了！你能精準捕捉到作者在這裡使用的「軍事隱喻」，代表你對文章整體的邏輯連結掌握得非常透徹。在最後一段中，Bagnato 博士將對抗細菌比喻成一場戰爭，他提到感染不能只靠「單一種類的武器 (one type of weapon)」，隨後引出需要一個「arsenal」。即便學生不確定這個單字的字典定義，從前文提到的：抗生素、光照、薑黃素（光敏劑）等多種手段的結合，便能推論出這裡指的是一套多元且豐富的應對方案，因此選擇 (E) 絕對是正確的判斷。
