When people perform experiments of any sort, the professional people only change one variable so that they know what is being changed. For instance if I compared the effect of the growth of flies, and one group had more food and cleaner water, and the other group had neither, it would be pointless. It would be pointless because even if the experimental results were a success, you wouldn't know for sure which variable caused the change, the water or the food variable. That's why there can only be one man-made variable at a time.
Hope this helps!

Balkan Peninsula is a headland of Greece, Bulgaria, Yugoslavia, Romania, Albania and Hungary under Ottoman Turkish rule. It is a geographic area in a southeastern part of Europe. The country takes the name from Serbian-Bulgarian border to the Black Sea’s Balkan Mountains. The geography was rotating around its three characteristics: its mountains, its rivers, and its area’s situation. The Peninsula itself is a triangular shape with a broad northern borderline, straitening to a tip as it extends to the south surrounded by the Black, the Aegean, the Mediterranean and the Adriatic Seas; they served each other as barriers and access points. Balkan is different from other peninsulas, it is not being secluded from nearby regions. Most of the ethnic groups in the region were entering in the access points of Romania in the northeast, Ukraine in the steppe regions, Danube and Hungarian in the northwest. Balkan is surrounded by 3 sides of water; the neighboring regions to the east, west, or south, the narrow channels of Bosphorus and the Dardanellas which are the natural passage between Anatolia and Balkans, and beyond Asia. Balkan is unsurprisingly a region that has been intersections for traffic accessing to and from all these destinations.
