问题如下：
The global bond benchmark in Exhibit 3 that is least appropriate
for Kiest to use is the:
选项：
A.Global Aggregate Index.
B.Global High Yield Index.
C.Global Aggregate GDP Weighted Index
解释：
B
is correct. Kiest has a young workforce and thus a long-term investment
horizon. The Global Aggregate and Global Aggregate GDP Weighted Indexes have
the highest durations (7.73 and 7.71, respectively) and would be appropriate
for this group. Global High Yield is the least appropriate due to its
relatively shorter duration.
为什么不选A，market-cap-weighted不是更容易导致Bums problem了。而Bums problem是不好的。而B选项避免了Bums problem，是好的benchmark
