Researchers in the Netherlands studied the effects of parental care giving in European kestrels over 5 years. The researchers transferred chicks among nests to produce reduced broods (three or four chicks), normal broods (five or six), and enlarged broods (seven or eight). They then measured the percentage of male and female parent birds that survived the following winter. (Both males and females provide care for chicks.) Which of the following is a conclusion that can be drawn from this graph?

Which of the following statements about the selection pressure is incorrect?

a.If survival of juveniles and adult is poor then selection favours a single act of reproduction

b.If survival of juveniles and adult is poor and unpredictable then selection favours repeated reproduction and long reproductive life

c.If the environment is stable then selection favours a single act of reproduction.

d.If survival of juveniles is very poor and unpredictable but adult are more likely to survive then selection favours repeated reproduction and long reproductive life

e.If survival of adult is unpredictable but juveniles are more likely to survive then selection favours a single act of reproduction
