Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Input: Consider Input: Cis-regulatory modules are non-protein-coding regions of DNA essential for the control of gene expression. One class of regulatory modules is embryonic enhancers, which drive gene expression during development as a result of transcription factor protein binding at the enhancer sequences. Recent comparative studies have begun to investigate the evolution of the sequence architecture within enhancers. These analyses are illuminating the way that developmental biologists think about enhancers by revealing their molecular mechanism of function.

Output: Are human enhancers or promoters evolving faster?


Input: Consider Input: Restless legs syndrome/Willis-Ekbom disease (RLS/WED) is commonly seen in patients with end-stage renal disease (ESRD), but this condition has not been properly recognized. The prevalence of RLS/WED in ESRD shows the ethnic variation (7%-68%), with the similar tendency of primary RLS/WED. Although RLS/WED in ESRD is defined in secondary RLS/WED, the factors of ESRD that are involved in the genesis of RLS/WED remain unknown. Even after renal transplantation, RLS/WED symptoms do not completely disappear, and genetic predisposition to RLS/WED may play an important role in causing RLS/WED. Long-term intervention for RLS/WED and ESRD will be necessary.

Output: Willis-Ekbom disease is also known as?


Input: Consider Input: The James Bay mine is one of the largest lithium mines in Canada.


Output: What product does James Bay mine make?
