Choosing 3 and 7 seems the most intuitive to me. 3 to move to inaccessible places with like glass windows as separation. 7 to check if containers are empty or not.

I would take the toaster one just so I could mess with my friends

1 and 2, but really only 1. If I can talk to oysters then I can figure out how to grow black pearls better and make some serious cash. If the oysters decide they don’t want to help then I can sell gravel.

I will make 10's to 100's of thousands paving roads with gravel and be more than willing to pave roads for people who can't maybe afford it without consequence.

Empty containers may be profitable as well since I could verify which shipping containers could be skipped for further processing, saving hundreds to thousands of hours of time, over time.

I'm going with 7 and 8. I'd publish a series of books on the Khitan language, get that bumped to the top of google when my name is searched, generally come off as interesting, then attempt to go viral playing shell game with randos on a boardwalk in an attempt to get noticed and land on Deal or No Deal or something like that. Then I'd snag the Guinness Book of World Records title for a couple things along the lines of shell game. Once I have a very modest amount of name recognition, I make a company selling rice cakes in such flavors as Buffalo Wing and Beef Jerky because that's a totally untapped market, in hopes of selling out to Frito Lay or whoever

Definitely #5 so I can shut up that Demented Toaster!

Do I have to pick two? Because I just want #6

1 and 2. The gravel to sell and the oysters to get a sense of how communications with other animals work. If I can communicate with an oyster, my understanding of communication could potentially extrapolate to higher animals.

7 and 3, no contest. With the ability to see inside containers and short teleport, a person could become a master thief fast

3 and 5 are a potentially broken combo. In particular if "control a toaster" means control and not just "operate", since then it's basically toasterkinesis, or being able to instantly turn any toaster into a bomb. "teleport up to 10 inches away sounds like it wouldn't be too useful but it does, in principle, allow you to phase out incoming bullets and a fair amount of lateral blade hits if you time it right.

6 and 7 could have some interesting, niche uses in some fields. 6 for example could be used for intimidation if "10 hours younger" is interpreted chronologically: even after taking a serious wound, you'd look pristine for around 10 hours so it might be used to scare or distract some enemies.

I'm... not even sure what 4 or 9 could ever be used for.

Time to disrupt the gravel market

Holy smokes, 2?? Obviously see inside empty containers and teleport up to 7 inches!

I'd give anything to be able to tell at a glance what boxes I don't need to open when looking for something and get out of nearly any tight spot or tangle.

5 If you want to see the world burn

Marvel 's writers picking up next super power

Spam teleporting hacks plus easy hiding using the teleport ability? Heckle yeah

1 and 8. I seek knowledge. A scholar, if you will.

10 hours younger than what?
