Answer:
200 CE.
Explanation:
The Silk Road was a network of routes through Central Asia, along which trade was conducted for many centuries between China and eastern Asia on the one hand and the Middle East and the Mediterranean on the other. For centuries, from classical times to the late Middle Ages, the Silk Road was the most important connection between East and West.
The western part of the route was completed in the 5th century BC, while the Central Asian portion of the route was already in use around 115 BC during the Han dynasty. Land trade declined in the Middle Ages, when it shifted to maritime transport.
Answer:
The port of Gwadar would provide China with an alternate and shorter route for energy imports from the Middle East, thereby reducing shipping costs and transit times, in addition to its importance in reducing Chinese reliance on the Malacca Sea and South China Sea routes.
Answer: Some geographic areas have obvious natural advantages that result in cluster formation. For example, proximity to a large port will attract exporting firms or areas rich in minerals will attract clusters of mining firms. In addition, there are three well-established reasons why firms choose locate in close proximity. The cost of transporting goods is reduced when firms are located close to their customers or suppliers. Input suppliers can exploit economies of scale in large clusters of downstream firms who, in turn, benefit from timely delivery and lower inventory costs.
Explanation: There are various types of clustering are that include:
^ Connectivity-based Clustering (Hierarchical clustering)
^ Centroids-based Clustering (Partitioning methods)
^ Distribution-based Clustering.
^ Density-based Clustering (Model-based methods)
^ Fuzzy Clustering.
^ Constraint-based (Supervised Clustering)
