a$)$ Use four different search engines $($yahoo$.$ca$,$ duckduckgo.com, google.ca$,$ and bing.ca$)$ to perform a search on a controversial topic of your choice. After performing a few queries, rank the four search engines based on what you find to be LEAST biased to MOST biased. $[1$ pt for ranking$]$ Here, LEAST BIASED is in the sense that it would not hide, filter, or reduce the ranking of the search results. MOST BIASED is that it intentionally filters controversial results or results that do not align with the engine$$s corporate policies. Support your answer with an actual example of your choice, clearly explaining the case supporting or refuting the presence of bias in each of the $4$ search engines. $($PS: it is possible to have a tie between search engines as they may yield similar results$).[2$ pts for explanations with an example demonstrating the bias$]$

b$)$ What are $2$ positive and $2$ negative impacts of Wikipedia? Support your answer with evidence drawn from credible references. $[2$ pts including reference$($s$)]$

c$)$ What is Web$3\mathrm{.}0,$ and how does it improve on Web$2\mathrm{.}0($provide two advantages$)?[2$ pts$]$

d$)$ Let$$s examine Chat GPT $($latest edition$)$ How would you construct a query dialogue request to demonstrate that it has or does not have a bias toward a sensitive subject? Briefly explain how you would design a test to demonstrate bias $[1$ pt$]$ and demonstrate by capturing the output $($brief$/$one sentence test$)$ of an example on a topic of your choice $[2$ pts$].$
