The Drake Equation Calculates the Number of Technically Advanced Civilizations

question 44

Multiple Choice

The Drake equation calculates the number of technically advanced civilizations in the Galaxy as a product of seven factors: R* fp nₑ fl fᵢ fc L.In the sample calculation in the text,these values are taken as 1 × 1 × 0.1 × 1 × 1 × 1 × 100 = 10.If we were to redo the calculation,increasing each increasable factor by a multiple of ten,what would the result be?

• A) 10
• B) 10⁴
• C) 10⁶
• D) 10⁸
