To find the proper base words that will fit into the sentences, it is very important to examine the context of these sentences. For example, when matters relating to the economy are discussed as in the case of the fifth and ninth sentences, then the right base word should be "economy".
Also, when matters relating to specialization in a field are discussed, as in the case of the first and eight sentences, the right base word will be "consult". A consultant is an expert in a field who gives professional advice. A specialist in a medical field is also a consultant so this fits into the contexts of the first and eight sentences.
