Andrea 想要触达更多具有类似职场特征的会员，她应该考虑使用哪些功能？请选择所有合适选项。

The Audience Expansion feature (广泛投放工具) is designed to help advertisers reach more LinkedIn members who share similar professional characteristics with their target audience. It intelligently expands campaign reach by identifying users with attributes like job title, industry, or skills that align with the defined audience, even if they don't perfectly match the initial targeting criteria. This is ideal for Andrea's goal of finding more members with similar workplace traits. Website Retargeting focuses on re-engaging users who have previously visited a website, not on finding new, similar audiences. Lead Gen Forms are used for capturing lead information directly on LinkedIn, not for audience expansion.
