Here is a question about this article: Like other settled, agrarian societies in history, those in the Indian subcontinent have been attacked by nomadic tribes throughout its long history. In evaluating the impact of Islam on the sub-continent, one must note that the northwestern sub-continent was a frequent target of tribes raiding from Central Asia. In that sense, the Muslim intrusions and later Muslim invasions were not dissimilar to those of the earlier invasions during the 1st millennium. What does however, make the Muslim intrusions and later Muslim invasions different is that unlike the preceding invaders who assimilated into the prevalent social system, the successful Muslim conquerors retained their Islamic identity and created new legal and administrative systems that challenged and usually in many cases superseded the existing systems of social conduct and ethics, even influencing the non-Muslim rivals and common masses to a large extent, though non-Muslim population was left to their own laws and customs. They also introduced new cultural codes that in some ways were very different from the existing cultural codes. This led to the rise of a new Indian culture which was mixed in nature, though different from both the ancient Indian culture and later westernized modern Indian culture. At the same time it must be noted that overwhelming majority of Muslims in India are Indian natives converted to Islam. This factor also played an important role in the synthesis of cultures.
What is the answer to this question: What type of new Indian culture was formed from this mixture of cultures?

So... mixed

Here is a question about this article: The BBC also introduced Ceefax, the first teletext service, starting in 1974. This service allows BBC viewers to view textual information such as the latest news on their television. CEEFAX has not made a full transition to digital television, instead being replaced by the new interactive BBCi service.
What is the answer to this question: What kind of service was Ceefax?

So... teletext

Here is a question about this article: Theophrastus wrote some of the earliest descriptions of plants and animals, establishing the first taxonomy and looking at minerals in terms of their properties such as hardness. Pliny the Elder produced what is one of the largest encyclopedias of the natural world in 77 AD, and must be regarded as the rightful successor to Theophrastus. For example, he accurately describes the octahedral shape of the diamond, and proceeds to mention that diamond dust is used by engravers to cut and polish other gems owing to its great hardness. His recognition of the importance of crystal shape is a precursor to modern crystallography, while mention of numerous other minerals presages mineralogy. He also recognises that other minerals have characteristic crystal shapes, but in one example, confuses the crystal habit with the work of lapidaries. He was also the first to recognise that amber was a fossilized resin from pine trees because he had seen samples with trapped insects within them.
What is the answer to this question: In what year did Pliny the Elder publish the largest encyclopedia?

So...
77 AD
