Answer 1

having long been interested in a career in sicial work是现在分词短语的完成式作原因状语，相当于状语从句because I have long been interested in a career in sicial work。
which will allow me to combine my analytical thinking skills with the pursuit of social justice是非限制性定语从句，其修饰的先行词是having long been interested in a career in sicial work这件事。
i now feel that i have accumulated the necessary experience and education to begin a formal pursuit in this field是主句，其中that i have accumulated the necessary experience and education to begin a formal pursuit in this field又是宾语从句，作feel的宾语。
wth X College offering the best curriculum for my needs是介词短语作状语，修饰谓语have accumulated。
