Input: Read this: Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. Rub-on dry transfers of common component footprints increased efficiency. Traces were made with self-adhesive tape. Pre-printed non-reproducing grids on the mylar assisted in layout. To fabricate the board, the finished photomask was photolithographically reproduced onto a photoresist coating on the blank copper-clad boards.
Question: What kind of metal coated the blank boards used to make PCBs?

Output: copper

QUES: Even though most ethnic groups prefer to communicate in their own languages, English as the official language is widely used for education, business transactions and for official purposes. English as a first language is used only by a small minority of the country's urban elite, and it is not spoken at all in some rural areas. Hausa is the most widely spoken of the 3 main languages spoken in Nigeria itself (Igbo, Hausa and Yoruba) but unlike the Yorubas and Igbos, the Hausas tend not to travel far outside Nigeria itself.[citation needed]

What is the most popular language in Nigeria?

In February 1939, he received news from his sisters that his mother was dying. On 10 February 1939, Pope Pius XI died. Roncalli was unable to see his mother for the end as the death of a pontiff meant that he would have to stay at his post until the election of a new pontiff. Unfortunately, she died on 20 February 1939, during the nine days of mourning for the late Pius XI. He was sent a letter by Cardinal Eugenio Pacelli, and Roncalli later recalled that it was probably the last letter Pacelli sent until his election as Pope Pius XII on 2 March 1939. Roncalli expressed happiness that Pacelli was elected, and, on radio, listened to the coronation of the new pontiff.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did he hear that his mother was dying?
Ah, so.. February 1939

Context and question: On Dell and Toshiba laptops, the port is marked with the standard USB symbol with an added lightning bolt icon on the right side. Dell calls this feature PowerShare, while Toshiba calls it USB Sleep-and-Charge. On Acer Inc. and Packard Bell laptops, sleep-and-charge USB ports are marked with a non-standard symbol (the letters USB over a drawing of a battery); the feature is simply called Power-off USB. On some laptops such as Dell and Apple MacBook models, it is possible to plug a device in, close the laptop (putting it into sleep mode) and have the device continue to charge.[citation needed]
On what laptops are the USB ports marked with a USB symbol with an added lightening bolt icon?
