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

Input: Consider Input: TransLink is urging customers to avoid non-essential travel today and to stay home where possible in the difficult weather conditions. TransLink chief executive officer Peter Strachan said bus and train services were continuing to run where possible, however all CityCat and CityFerry services had been cancelled until further notice. "These are extremely difficult conditions for South East Queensland---we are running essential services where possible but safety remains to be the most important," Mr Strachan said. "Severe weather and associated flooding has impacted on all modes of public transport, with bus, ferry and train services all impacted to varying degrees. "If you are planning to use public transport at anytime over the next few days, then I would recommend you check that your intended service is still running." Service disruptions for today include: l City network trains running hourly on all lines. l Bus diversions, delays and cancellations in some regions, particularly across Brisbane, Ipswich and the Sunshine Coast. l CityCat and CityFerry services cancelled. Queensland Rail Chief Executive Officer Paul Scurrah said rising waterways had closed some train lines, and road closures and damage to property throughout the South-East had contributed to a shortage of available rail employees. "We intend to run trains hourly on all lines, similar to the timetable we operate on Christmas Day. We will also be looking to run other additional services to meet demand as required. At this stage we will run services stopping at all stations which will depart at the same time on the hour, however, this is all subject to the weather conditions and the availability of traincrew." Mr Scurrah encouraged all customers to visit the Translink website for specific departure times for their station, and asked for patience in the event of delays. "Queensland Rail appreciates that reduced services may cause disruptions but it is simply unavoidable. We have a dedicated and experienced team monitoring the situation around the clock and will be working to reopen the network as soon as practicably possible," Mr Scurrah said. The latest service disruption information is available on the TransLink website www.translink.com.au.

Output: Which means of transport is NOT available during the special period?


Input: Consider Input: In late 1911, she worked as a secretary for Sun Yat-sen, a job later succeeded by her sister, Soong Ching-ling, who later became Madame Sun Yat-sen. Soong Ai-ling met her future husband, Kung Hsiang Hsi, in 1913, and married the following year in Yokohama.

Output: Which woman was the sister of Soong Ai-ling?


Input: Consider Input: GATA-1 and the ets factor PU.1 have been reported to functionally antagonize one another in the regulation of erythroid versus myeloid gene transcription and development. The CCAAT enhancer binding protein epsilon (C/EBPepsilon) is expressed as multiple isoforms and has been shown to be essential to myeloid (granulocyte) terminal differentiation. We have defined a novel synergistic, as opposed to antagonistic, combinatorial interaction between GATA-1 and PU.1, and a unique repressor role for certain C/EBPepsilon isoforms in the transcriptional regulation of a model eosinophil granulocyte gene, the major basic protein (MBP). The eosinophil-specific P2 promoter of the MBP gene contains GATA-1, C/EBP, and PU.1 consensus sites that bind these factors in nuclear extracts of the eosinophil myelocyte cell line, AML14.3D10. The promoter is transactivated by GATA-1 alone but is synergistically transactivated by low levels of PU.1 in the context of optimal levels of GATA-1. The C/EBPepsilon(27) isoform strongly represses GATA-1 activity and completely blocks GATA-1/PU.1 synergy. In vitro mutational analyses of the MBP-P2 promoter showed that both the GATA-1/PU.1 synergy, and repressor activity of C/EBPepsilon(27) are mediated via protein-protein interactions through the C/EBP and/or GATA-binding sites but not the PU.1 sites. Co-immunoprecipitations using lysates of AML14.3D10 eosinophils show that both C/EBPepsilon(32/30) and epsilon(27) physically interact in vivo with PU.1 and GATA-1, demonstrating functional interactions among these factors in eosinophil progenitors. Our findings identify novel combinatorial protein-protein interactions for GATA-1, PU.1, and C/EBPepsilon isoforms in eosinophil gene transcription that include GATA-1/PU.1 synergy and repressor activity for C/EBPepsilon(27).


Output: Which gene controls the expression of GATA-1 isoforms?
