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

Ex Input:
Heme is critical for a variety of cellular processes, but excess intracellular heme may result in oxidative stress and membrane injury. Feline leukemia virus subgroup C receptor (FLVCR1), a member of the SLC49 family of four paralogous genes, is a cell surface heme exporter, essential for erythropoiesis and systemic iron homeostasis. Disruption of FLVCR1 function blocks development of erythroid progenitors, likely due to heme toxicity. Mutations of SLC49A1 encoding FLVCR1 are noted in patients with a rare neurodegenerative disorder: posterior column ataxia with retinitis pigmentosa. FLVCR2 is highly homologous to FLVCR1 and may function as a cellular heme importer. Mutations of SLC49A2 encoding FLVCR2 are observed in Fowler syndrome, a rare proliferative vascular disorder of the brain. The functions of the remaining members of the SLC49 family, MFSD7 and DIRC2 (encoded by the SLC49A3 and SLC49A4 genes), are unknown, although the latter is implicated in hereditary renal carcinomas. SLC48A1 (heme responsive gene-1, HRG-1), the sole member of the SLC48 family, is associated with the endosome and appears to transport heme from the endosome into the cytosol.

Ex Output:
Which SLC family is FLVCR1 a member of?

Riociguat (Adempas(®)), an oral first-in-class soluble guanylate cyclase (sGC) stimulator, is under global development by Bayer Healthcare Pharmaceuticals Inc. for the treatment of adult patients with inoperable or chronic/persistent chronic thromboembolic pulmonary hypertension (CTEPH) and for the treatment of adult patients with pulmonary arterial hypertension (PAH). The drug directly stimulates sGC in a nitric oxide independent manner, thereby increasing the sensitivity of sGC to nitric oxide, leading to increased cyclic guanosine monophosphate generation (a key signalling molecule involved in regulating vascular tone, proliferation, fibrosis and inflammation). Riociguat is the world's first approved pharmacotherapy for CTEPH, with its first global approval in this indication occurring in Canada. It has subsequently been approved in the USA for the treatment of patients with CTEPH and also received its first global approval in patients with PAH in the USA. It is undergoing regulatory review for these indications in Europe and for use in patients with CTEPH in Japan. This article summarizes the milestones in the development of riociguat, leading to its first global approvals in patients with CTEPH and PAH.

What is generic name of drug Adempas?


Ex Input:
When the order was restored, Murad Pasha marched against Abbas I who was in Tabriz in 1610. Although the two armies met in Accay, north of Tabriz, no engagement or action took place. Due to the problems in the logistics, supply chain and the approaching winter Murad Pasha withdrew his forces to Diyarbakr. While being engaged in diplomatic correspondence with Abbas I for peace and preparing his army for another campaign at the same time he died on 5 August 1611 when he was older than 90. Nasuh Pasha was appointed as the new grand vizier and the commander of the eastern armies. He sued for peace, too, and accepted the proposal of the Safevid side in 1611. The Treaty of Nasuh Pasha was signed on 20 November 1612. The agreement secured the 1555 borders envisaged by the Peace of Amasya. Shah Abbas however, committed himself to send 200 bales of raw silk annually.

Ex Output:

Which happened first, Murad marching against Abbas or the signing of the Treaty of Nasuh Pasha?
