Input: Read this: Dietary deficiencies in developing countries can be combated by promoting better eating practices. Supplementation with vitamin A and/or zinc. Zinc supplementation proved successful showing a significant decrease in the incidence of diarrheal disease compared to a control group.

Development of a supplementation strategy should take into consideration the fact that vitamin A supplementation was less effective in reducing diarrhea incidence when compared to vitamin A and zinc supplementation, and that the latter strategy was estimated to be significantly more cost effective.

Input: Read this: Once at Golgotha, Jesus was offered wine mixed with gall to drink. Matthew's and Mark's Gospels record that he refused this. He was then crucified and hung between two convicted thieves. According to some translations from the original Greek, the thieves may have been bandits or Jewish rebels. According to Mark's Gospel, he endured the torment of crucifixion for some six hours from the third hour, at approximately 9 am, until his death at the ninth hour, corresponding to about 3 pm. The soldiers affixed a sign above his head stating "Jesus of Nazareth, King of the Jews" in three languages, divided his garments and cast lots for his seamless robe. The Roman soldiers did not break Jesus' legs, as they did to the other two men crucified (breaking the legs hastened the crucifixion process), as Jesus was dead already. Each gospel has its own account of Jesus' last words, seven statements altogether. In the Synoptic Gospels, various supernatural events accompany the crucifixion, including darkness, an earthquake, and (in Matthew) the resurrection of saints. Following Jesus' death, his body was removed from the cross by Joseph of Arimathea and buried in a rock-hewn tomb, with Nicodemus assisting.
