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

Input: Consider Input: Patients with multiple myeloma (MM) experience pathologic fractures, bone pain, hypercalcemia, neurologic symptoms, and renal insufficiency with substantial morbidity and mortality. Bisphosphonates have been used successfully for the management of MM-related bone disease. Increased incidence of osteonecrosis of the jaw has been observed in patients with cancer receiving bisphosphonate therapy. Recent advances in the pathobiology of MM-related bone disease and other cancer-related bone metastases have led to the identification of novel therapeutic targets, such as receptor activator of nuclear factor-kappaB (RANK); its ligand (RANKL); and a decoy receptor, osteoprotegerin, for the development of potential targeted agents. Initials studies have demonstrated that targeting RANK/ RANKL signaling with the fully human monoclonal antibody denosumab prevented skeletal complications in patients with MM and other cancers with bone metastases. Ongoing studies evaluating the clinical utility of denosumab in cancer- related bone destruction have been discussed. In addition, several potential targets, such as macrophage inflammatory protein-1alpha, chemokine receptors 1 and 5, interleukin-3, and Wnt signaling, are b riefly described.

Output: To the ligand of which receptors does Denosumab (Prolia) bind?


Input: Consider Input: Brigadier Sir Iltyd Nicholl Clayton CBE (1886 -- 30 June 1955) was a British Army officer notable for his attachment to the Middle East Office in Cairo during and after World War II and his involvement in the formation of Arab League and formulation of post-war British policy in the Middle East.

Output: Who did Iltyd Nicholl Clayton serve for?


Input: Consider Input: Wouter Claes (born 28 October 1975 in Leuven, Belgium) is a male left-handed Belgian badminton player.


Output: What is the sex or gender of Wouter Claes?
