What was the difference in the percentage of R&D expenditure relative to GDP between Finland and Sweden in 2019? option_A: 0.1% option_B: 0.2% option_C: 0.3% option_D: 0.4% option_E: None of the above explanation: To calculate the difference between Finland and Sweden in 2019, the values for each country in that year are taken: Finland = 3.6% and Sweden = 3.5%. The difference is 3.6% - 3.5% = 0.1%. However, the correct calculation is the absolute difference between the two values, which is 0.1%. Options A and D are designed to confuse: A represents Sweden's value in 2019 (3.5%) as the difference, and D is the correct difference. Option C is a calculation error by adding the values instead of subtracting them. Option B represents an interpretation error by calculating the difference as if it were a percentage increase instead of an absolute difference. Option E is incorrect because there is a correct answer available.
