Based on Table 53.1, which age interval for female Belding's ground squirrels exhibits both a death rate greater than 0.500 and an average number of female offspring per female greater than 2.00?

  • A: 0-1 years
  • B: 5-6 years
  • C: 8-9 years
  • D: 9-10 years

Explanation

By examining Table 53.1: - For 0-1 years: Death Rate = 0.614 >0.500 , Offspring = 0.00 <2.00 . - For 5-6 years: Death Rate = 0.526 >0.500 , Offspring = 2.08 >2.00 . This matches both criteria. - For 8-9 years: Death Rate = 0.750 >0.500 , Offspring = 1.93 <2.00 . - For 9-10 years: Death Rate = 1.00 >0.500 , Offspring = 1.58 <2.00 . Only the 5-6 years age interval satisfies both conditions.
