Those may make some contribution, and if they can do better than I expect, so much the better, but my key point here is that we're going to have to work on each of these five, and we can't give up any of them because they look daunting, because they all have significant challenges.
Oni možda mogu dati neki doprinos, i ako budu bolji od mojih očekivanja, tim bolje, ali moja je poanta u tome da ćemo morati raditi na svakom od ovih pet, i ne možemo odustati od bilo kojeg od njih jer izgleda obeshrabrujuće, jer svi oni imaju značajne izazove.
