Please help me with my hw, explanation appreciated!

Below find cross-validated ROC curves for Model C and Model E described as follows: Model Covariates included C Age, education, disease categories, BMI, mobility disability, ADL disability E Model C covariates + need more emotional support + life events in last year MODEL C MODEL E on AUC=0.7145 AUC#0.7016 6:00 a. Model C predictively discriminates those dying from those not dying moderately well; adding need for more emotional support and life events occurrence slightly improves the predictive discrimination. b. The association of need for more emotional support and/or life events occurrence with death is confounded by the covariates in Model C. c. Death is statistically significantly associated with need for more emotional support and life events occurrence, after adjusting for the covariates in Model C. d. Model C predictively discriminates those dying from those not dying moderately well; adding need for more emotional support and life events occurrence does not improve the predictive discrimination. e. There is no statistically significant association of death with need for more emotional support or life events occurrence, after adjusting for the covariates in Model C
