The answer is '4'.
The Soviet economy crumbled further due to the heavy military cost of the invasion.
The U.S. provided financial support to push them out and shorten the conflict. The Red Army did suffer a loss of face but the collapse of the Soviet Union happened because military expenses drained their economy to such an extent that normal, everyday expenses could not be met.
Answer:
A mixed economic system protects private property and allows a level of economic freedom in the use of capital, but also allows for governments to interfere in economic activities in order to achieve social aims.
Explanation:
The Constitution protects property rights through the Fifth and Fourteenth Amendments’ Due Process Clauses and, more directly, through the Fifth Amendment’s Takings Clause: “nor shall private property be taken for public use without just compensation.” There are two basic ways government can take property: (1) outright, by condemning the property and taking title; and (2) through regulations that take uses, leaving the title with the owner — so‐called regulatory takings. In the first case, the title is all too often taken not for a public but for a private use; and rarely is the compensation received by the owner just. In the second case, the owner is often not compensated at all for his losses; and when he is, the compensation is again inadequate.
The Supreme Court decides to hear a case based on at least four of the nine Justices of the Supreme Court agreeing to grant the Petition for Certiorari. If four Justices agree to grant the petition, the Supreme Court will consider the case.
