A battle in which Soviet city marked the beginning of Germany's collapse in the Soviet Union?

Stalingrad.
The problem was, Germany was trying to fight a war on two fronts, which is never a good idea, no matter how powerful of a military you have.
The Battle of Stalingrad in 1942 resulted in a Soviet victory and the complete decimation of the Germany 6th Army. The Soviet forces had heavy losses, but did manage to push back Axis forces from the ground they took over that summer.

Hello. This question is incomplete. The full question is:

Read the scenario. Luca, a landowner who employed numerous servants, and Fabian, the owner of a grocery store, are debating politics. Fabian believes that most individuals will make good choices concerning government, and Luca says,“Well, what about people who are not well-informed? They could cause a lot of trouble.” According to the discussion in the scenario, which is most likely true? Luca is conservative; Fabian is liberal. Luca is liberal; Fabian is conservative. Both Luca and Fabian are conservative. Both Luca and Fabian are liberal.

Luca is conservative; Fabian is liberal

Explanation:

Individuals entitled as liberals are committed to the philosophy that states that the government is primarily responsible for the well-being of the population, through programs that encourage equality between people, the free market economy, gay marriage, the confirmation of women's rights, the release of marijuana use, among other factors. Conservatives, on the other hand, support the philosophy that states that the well-being of the population depends exclusively on the individual responsibility of individuals, in addition, they support traditional values ​​such as the ban on same-sex marriage, the limitation of women's rights, education based on religion, among other factors.

Based on that, we can say that Fabian is a liberal, since he believes that the government has what it takes to promote the civil and social well-being of citizens. Luca, however, does not agree with this, but believes that citizens must guarantee their well-being. Luca is a conservative.
