i think you mean antibiotic ... but Alexander Fleming was the one who advanced the antibiotic (world) and was responsible for creating these categories of medicine... this affected the 20th century because millions of people use antibiotics everyday and without them... many diseases would still affect people without a cure
In some instances, Federal officials expedited the naming process by furnishing the names themselves, and invariably the name would be the same as that of the freedman’s most recent master. But these appear to have been exceptional cases; the ex-slaves themselves usually took the initiative—like the Virginia mother who changed the name of her son from Jeff Davis, which was how the master had known him, to Thomas Grant, which seemed to suggest the freedom she was now exercising.

Among the natural disasters or natural dangers that a farmer of the Middle East could face, the most common are:
Drought: One of the main problems in the Middle East is droughtiness. Water scarcity have always been a problem in this region and being a farmer in the middle of this situation could result in big problems when you grow your crops. A way to prevent this natural danger, would be by having enough water storage near the farm or crops and a better water management. It is highly important to check Drought monitors or Drought impacts to study where the farm could be less affected by this rough season.
Flooding: opposite to droughtiness, we could have the other face of the coin, that is tons of water that could negatively hit the crops. The pro during this season is that water can be storage in great amounts for the previous season, however, during this situation would be useful to count with channels that could spread the water and to invest in infrastructure that could save the crops from getting tons of water into them. And once again, check the recent studies of the previous weather reports.
