The question type is inference- to infer conclusion (that must be true) based on the information provided
Quick snapshot of information-
1. Number of public works projects as well % expenditure spent on infra has consistently declined in Soviet Union from 1970 to 1980 (15%). The highest % of GDP spent on infra by SU was in 1958 at 24%
2. In the said period (from 1958 to 1980), the % of GDP spent on infra has increased for India and Argentina
Pre-thinking: Inferences that can be drawn are-
1. SU's expenditure percentage for infra has consistently declined to 15% (should be lowest in 1980 since 1958)
2. While the percentage for SU has declined on infra, we still don't know the actual numbers for any countries
3. The actual spending given for SU is of public works project and not the total expenditure on infra
Analyzing answer choices:
A. We have no information at all about the total GDP of any country, so no correlation can be built at all- Eliminate
B. Incorrect
C. Out of scope - Incorrect
D. Incorrect again- no such information is provided. Who knows, India and Argentina may already spend more on PW projects than SU
E. Correct- See the prethinking. Argentina's % spending has increased in this period, so its max should be 12% while SU's minimum in this period should be 15%
