Statement I: The US Army built the historic Stilwell Road in 1943 running from Ledo in Assam to the China-Burma Road- Statement I : The objective was to form a link with the Bengai-Assam Railway and carry support for the US and the UK warfare against Japan.

Statement I is true as the US Army, under General Joseph Stilwell, oversaw the construction of the historic Stilwell Road (originally the Ledo Road) starting in late 1942 and continuing through 1943. The road ran from Ledo in Assam, India, to connect with the old Burma Road, eventually reaching Kunming, China [t1, t3, t4]. Statement II is also true and provides the correct explanation for Statement I. The primary strategic objective was to establish a land supply route to support Allied forces (US, UK, and Chinese) against Japanese aggression after the original Burma Road was cut in 1942 [t1, t5, t6]. Ledo was specifically chosen because it was a railhead of the Bengal-Assam Railway, allowing supplies arriving by rail from Indian ports like Calcutta to be transferred to trucks for transport into the China-Burma-India (CBI) theater [t1, t5].
