请解释一下这道题

问题如下：

An investment firm has decided to start integrating ESG factors into developing its investment recommendations. The firm establishes a separate team of ESG analysts made up of recruits from the business sustainability programs at several universities. Also, the firm subscribes to multiple ESG service providers for access to data and ratings. Which of the firm’s actions will best help the firm overcome the challenges of ESG integration?

选项：

A.The subscriptions for data sources

B.The recruitment of team members

C.The establishment of a separate team

解释：

A is correct. Using multiple sources of information is one way to overcome the challenges of ESG integration for a firm. The low correlation between data providers and datasets in the ESG market is a challenge in the industry, but using a single source can cause a firm to not consider different opinions and lead to poor outcomes from a potentially incomplete data field. A divergence in opinions can be helpful because it allows both positive and negative arguments to be considered. Establishing a separate team can move ESG expertise away from the investment decisions and may provide a challenge to integration. Hiring team members with sustainability training is useful, but if they are all junior members, as is implied if they are hired right out of university, their opinions are often not weighed as heavily as more senior analysts.
