Examine the webpages of Singapore River Cruise and DuckTours services to display the following using geospatial data in QGIS:

1. Routes of both services using line geometry layer(s), differentiating Singapore River Cruise service, DuckTours service (land and water), and any shared routes.
2. Main en-route attractions using point geometry layer(s), differentiating those that can be seen only with the Singapore River Cruise; those that can only be seen with the DuckTour (land and water); and those that can be seen from both. Include at least three (3) attractions for each classification.
3. Attribute table(s) of these main attractions, you should prepare the table including geographic data, postal code, attraction name, and other necessary notes (include at least two (2) notes).
4. How would you represent the most iconic tourist attractions en-route for tourism information? Why? What are some of the challenges that one can face when using QGIS tools for tourist attractions/routes representations?

Please show layers of the QGIS and screenshots. Thanks!
