Informal learning is one of three forms of learning defined by the Organisation for Economic Co-operation and Development (OECD). Informal learning occurs in a variety of places, such as at home, work, and through daily interactions and shared relationships among members of society. For many learners this includes language acquisition, cultural norms and manners. Informal learning for young people is an ongoing process that also occurs in a variety of places, such as out of school time, in youth programs at community centers and media labs.

The Hindu Shahis under Jayapala, is known for his struggles in defending his kingdom against the Ghaznavids in the modern-day eastern Afghanistan and Pakistan region. Jayapala saw a danger in the consolidation of the Ghaznavids and invaded their capital city of Ghazni both in the reign of Sebuktigin and in that of his son Mahmud, which initiated the Muslim Ghaznavid and Hindu Shahi struggles. Sebuk Tigin, however, defeated him, and he was forced to pay an indemnity. Jayapala defaulted on the payment and took to the battlefield once more. Jayapala however, lost control of the entire region between the Kabul Valley and Indus River.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what id Jayapala see a danger to his dynasty?
Ah, so.. consolidation of the Ghaznavids

Historically, major professional orchestras have been mostly or entirely composed of male musicians. Some of the earliest cases of women being hired in professional orchestras was in the position of harpist. The Vienna Philharmonic, for example, did not accept women to permanent membership until 1997, far later than the other orchestras ranked among the world's top five by Gramophone in 2008. The last major orchestra to appoint a woman to a permanent position was the Berlin Philharmonic. As late as February 1996, the Vienna Philharmonic's principal flute, Dieter Flury, told Westdeutscher Rundfunk that accepting women would be "gambling with the emotional unity (emotionelle Geschlossenheit) that this organism currently has". In April 1996, the orchestra's press secretary wrote that "compensating for the expected leaves of absence" of maternity leave would be a problem.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What year did the Vienna Philharmonic first accept women?
Ah, so..
