Answer:

Due to the cost and resource input (specially the land) required for producing ethanol

Extensor Group- The superficial extensors of the forearm are a group of six muscles situated in the superficial posterior compartment of the forearm. These muscles include the brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, extensor carpi ulnaris  and extensor digiti minimi.
