Based on the data in the table about investment in R&D and production in the European Union in 2023, what is the difference in millions of euros between the total value of registered patents in Germany and France, and what is the corresponding difference in total R&D expenditure between both countries? Select the option that correctly represents the difference in total R&D expenditure. option_A: 15.200 million euros option_B: 12.400 million euros option_C: 11.100 million euros option_D: 9.800 million euros option_E: None of the above Explanation: 1) Why the correct answer is correct: The correct answer D is based on the precise calculation of the difference in total R&D expenditure. According to the table, the total R&D expenditure of Germany is 74.300 million euros and that of France is 63.200 million euros. The difference is 74.300 - 63.200 = 11.100 million euros. The question specifically asks for the difference in total R&D expenditure, ignoring the patent data which is a distractor for the second part of the statement. 2) Why the incorrect options are incorrect: - Option D (12.400) is incorrect because it uses the number of registered patents per million inhabitants instead of the total expenditure, or it confuses the units. It is a metric trap. - Option D (9.800) is incorrect because it represents the difference in GDP per capita between both countries (20.500 - 10.700 = 9.800), not in R&D expenditure. It is a trap of using the wrong column (GDP/hab instead of R&D expenditure). - Option D (15.200) is incorrect because it sums the R&D expenditure values of Germany and France (74.300 + 63.200) instead of subtracting them, or it uses a different year (2022) where the difference was greater. It is an arithmetic operation trap. - Option D is incorrect because there is a correct answer among options C-D. 3) Quick tip: In the EPSO exam, identify immediately which specific metric the question is asking for (e.g., 'total expenditure') and mentally filter out distracting columns (like 'patents' or 'GDP/hab') before doing any calculation. Read the statement twice to ensure you have not confused the numerator and denominator or the correct year.
