Answer:
1-A: A cataract is another term for waterfall
2-E: Ex. European countries colonized North and South America centuries ago
3-F: Escarpment is a word for a steep cliff or slope
4-B: A topographic map shows the geographic features of an area
5-D: A tributary is a smaller stream that always flows into a bigger one
6-C: Veldt is another word for a plateau
The last statement is the correct answer. However, the second question is theoretically historically correct, for Иосиф Сталин (Joseph Stalin) practically controlled the entire government of the USSR with his oppressive ultra-authoritarian non-democratic Stalinist-"Communist" regime.
