问题如下：
The DoGood Fund’s approach to the aerospace and defense industry is
best described as:
选项：
A.positive screening
negative screening
thematic investing
解释：
The DoGood fund excludes companies based on specified activities (e.g.,
aerospace and defense), which is a process of negative screening. Negative or
exclusionary screening refers to the practice of excluding certain sectors or
companies that deviate from accepted standards in areas such as human rights or
environmental concerns.
A is incorrect because positive screening attempts to identify
companies or sectors that score most favorably regarding ESG-related risks
and/or opportunities. The restrictions on investing indicates that a negative
screen is established.
C is incorrect because thematic investing focuses on investing in
companies within a specific sector or following a specific theme, such as
energy efficiency or climate change. The DoGood Fund’s investment universe
includes all companies and sectors that have favorable ESG (no specific sectors
or screens) but with specific exclusions.
老师你好，没太看懂解释，不选A是不是因为选了所有（ALL）涉及ESG的公司，而不是最top的那几个所以不对呢？
