Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
One example: In 1582 the united provinces invited francis, duke of anjou to lead them; but after a failed attempt to take antwerp in 1583, the duke left the netherlands again. after the assassination of william of orange (10 july 1584), both henry iii of france and elizabeth i of england declined the offer of sovereignty. however, the latter agreed to turn the united provinces into a protectorate of england (treaty of nonsuch, 1585), and sent the earl of leicester as governor-general. this was unsuccessful and in 1588 the provinces became a confederacy. the union of utrecht is regarded as the foundation of the republic of the seven united provinces, which was not recognized by the spanish empire until the peace of westphalia in 1648.
Solution is here: In what year did francis, duke of anjou leave the netherlands?
Explanation: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

Now, solve this: Anticoagulation therapy is indicated for management of various clinical conditions to prevent adverse events and introduction of direct oral anticoagulants (DOACs) has ushered in a new era in anticoagulation therapy. Major advantages of DOACS include fewer drug interactions and that they do not need periodic monitoring. Several patients who were not on anticoagulation before due to older age, polypharmacy/drug interaction concerns, and logistics of periodic monitoring are now on anticoagulation with DOACs. Despite their many advantages, a challenge while prescribing DOACs is very limited availability of specific reversal agents and lack of understanding or guidance about the treatment strategy in case of major life threatening bleeding or need for urgent surgery. So far only one reversal agent has been approved by the Food and Drug Administration (FDA), idarucizumab for one of the DOACs i.e., dabigatran. Several other reversal agents are under final phases of development such as andexanet alfa and PER977 (ciraparantag) and will help in developing specific strategies for reversal of these agents. In this article, we review current strategies to manage bleeding with DOACs and provide guidance to clinicians of inhibiting LF activity in vitro and in cells, as well as in animal models of anthrax infection.
Solution:
Which drug can be reversed with idarucizumab?
