Prior to the 12th century, women accounted for less than one percent of the world’s Islamic scholars. However, al-Sakhawi and Mohammad Akram Nadwi have since found evidence of over 8,000 female scholars since the 15th century. al-Sakhawi devotes an entire volume of his 12-volume biographical dictionary al-Ḍawʾ al-lāmiʻ to female scholars, giving information on 1,075 of them. More recently, the scholar Mohammad Akram Nadwi, currently a researcher from the Oxford Centre for Islamic Studies, has written 40 volumes on the muḥaddithāt (the women scholars of ḥadīth), and found at least 8,000 of them.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What percentage of Islamic women were educated before the 1200s?
Ah, so.. less than one percent

The CD was planned to be the successor of the gramophone record for playing music, rather than primarily as a data storage medium. From its origins as a musical format, CDs have grown to encompass other applications. In 1983, following the CD's introduction, Immink and Braat presented the first experiments with erasable compact discs during the 73rd AES Convention. In June 1985, the computer-readable CD-ROM (read-only memory) and, in 1990, CD-Recordable were introduced, also developed by both Sony and Philips. Recordable CDs were a new alternative to tape for recording music and copying music albums without defects introduced in compression used in other digital recording methods. Other newer video formats such as DVD and Blu-ray use the same physical geometry as CD, and most DVD and Blu-ray players are backward compatible with audio CD.

Ah, so.. unanswerable

It should be noted that although 6-month-olds can recall information over the short-term, they have difficulty recalling the temporal order of information. It is only by 9 months of age that infants can recall the actions of a two-step sequence in the correct temporal order - that is, recalling step 1 and then step 2. In other words, when asked to imitate a two-step action sequence (such as putting a toy car in the base and pushing in the plunger to make the toy roll to the other end), 9-month-olds tend to imitate the actions of the sequence in the correct order (step 1 and then step 2). Younger infants (6-month-olds) can only recall one step of a two-step sequence. Researchers have suggested that these age differences are probably due to the fact that the dentate gyrus of the hippocampus and the frontal components of the neural network are not fully developed at the age of 6-months.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What part of the brain is fully developed in infants which can cause the memory differences in ages?
Ah, so..
unanswerable
