不好意思請問一下，第三題的手寫為什麼這個句子不需要加逗號？ （加逗號是非限定用法，主詞Singapore 是獨有無二且明確的，但卻不用加逗號感覺很怪怪的？）

以下是心統的題幹與問題 想請問第以下兩題是否有計算錯誤？

1. Any of you who have listened to children tell stories will recognize that, unlike adults, they tend to recall stories as a sequence of actions rather than as an overall plot. Their descriptions of a movie are filled with the phrase "and then...." An experimenter with supreme patience asked 50 children to tell her about a given movie. Among other variables, she counted the number of "and then..." statements, which is the dependent variable. The data follow: 18 15 22 19 18 17 18 20 17 12 16 16 17 21 23 18 20 21 20 20 15 18 17 19 20 23 22 10 17 19 19 21 20 18 18 24 11 19 31 16 17 15 19 20 18 18 40 18 19 16 簡單翻譯:心理學家請小孩描述電影情節,並記錄他們使用「然後」的次數,50 位小孩的次數 如上。

想詢問這個該如何證明？

of duration relat- ing to the maturity, yield, and coupon interest of the security being analyzed. Duration and Maturity A comparison of Tables 9-6, 9-3, and 9-7 indicates that duration increases with the maturity of a fixed-income asset or liability, but at a decreasing rate:4 OD OM > 0 d²D dM² <0 To see this, look at Figure 9-4, where we plot duration against maturity for a three-year, a two-year, and a one-year U.S. Treasury bond using the same yield of 4 This is the case for the vast majority of securities. It needs to be noted, however, that for bonds selling below par, duration increases at a decreasing rate up to a point. At long maturities (e.g., 50 years) dura- tion starts to decline. Few bonds in the market have a maturity long enough to see this decline.
