Answers to the Task 3: What extra information that cncordance provided me was , when I clicked on any word it gave me its use in sentences. This was not the only advantage that I took from it. I was be able to get a definition/descriptions about what the materials meant. I didn't understand what this second question wanted from me to explain. I think mostly the prepositions comes after the word 'materials' is being used. However, both 'enhanced' and 'authentic' take noun right after they are used. I think the stronger collocate of 'material' was 'for'.
