    What is “the Monitor” in Paragraph 1 most likely to be?

    正确答案： Newspaper.
    解析：
    推理题。根据题干定位至原文第一段。该段第一句说到：“My grandmother cut a recipe sometime in the 1940s or 1950s for ‘Mrs. Orr’s Chocolate Cake’ from the Monitor.”分析该句句意可知，因此该句中提到的“Mrs. Orr’s Chocolate Cake”应该是一个名人做蛋糕的专栏，报纸除了新闻还有其他栏目，由此可判断出奶奶应该是从“报纸”上的食谱专栏里剪贴下烹饪方法，因此原文中的the Monitor应该是一份报纸，故本题的正确答案为Newspaper。
