Solution of extra credit pop-up quiz

Solution of the Milka pop-up quiz (1 big mistake, two small mistakes):

Wrong sentence:

"This is our home, for the preservation of which we are strongly engaging ourselves, for example as "Official Sponsor of the Hohe Tauern National Park," or the sole use of renewable energies for the Milka production."

Right sentence:

"This is our home for the preservation of which we are strongly engaging ourselves, for example as Official Sponsor of the Hohe Tauern National Park, or as purporter/user of renewable energies for the Milka production."

What was wrong:
1) The "as" only referred to the word "sponsor," but not to "sole use." We function as sponsor, but do we function as sole use? No. We need two subjects here: "sponsor" and "user," "purporter," "fighter for," etc. This is what we stand for. We are sponsors and users, not a "use."

2) There should not be quotation marks around the Official Sponsor of the Hohe Tauern National Park; however, you need to capitalize the words, because it is an official title. It's like being an Official Sponsor of the Olympic Games. You don't need quotation marks around "Hohe Tauern National Park," either, because this is just the name of the park.

3) The first comma was redundant. You just need "our home for the preservation of which."

When the "as" refers to both subjects correctly, you have a parallelism (for good style): you function AS sponsor and AS user. (You can leave out the second "as," because it is a repetition.)

I gave 1 point for each of the small mistakes, but you really should have found the "as," for it is a wrong connection. It must refer to both things, not just to the sponsor.
