[EX Q]: Firstly conceived and still used today for optical storage devices (CD-RW drives, DVD drives, etc.), several manufacturers offer external portable USB hard disk drives, or empty enclosures for disk drives. These offer performance comparable to internal drives, limited by the current number and types of attached USB devices, and by the upper limit of the USB interface (in practice about 30 MB/s for USB 2.0 and potentially 400 MB/s or more for USB 3.0). These external drives typically include a "translating device" that bridges between a drive's interface to a USB interface port. Functionally, the drive appears to the user much like an internal drive. Other competing standards for external drive connectivity include eSATA, ExpressCard, FireWire (IEEE 1394), and most recently Thunderbolt.

[EX Q]: A day after announcing the attempt on his life, Nasser established a new provisional constitution proclaiming a 600-member National Assembly (400 from Egypt and 200 from Syria) and the dissolution of all political parties. Nasser gave each of the provinces two vice-presidents: Boghdadi and Amer in Egypt, and Sabri al-Asali and Akram al-Hawrani in Syria. Nasser then left for Moscow to meet with Nikita Khrushchev. At the meeting, Khrushchev pressed Nasser to lift the ban on the Communist Party, but Nasser refused, stating it was an internal matter which was not a subject of discussion with outside powers. Khrushchev was reportedly taken aback and denied he had meant to interfere in the UAR's affairs. The matter was settled as both leaders sought to prevent a rift between their two countries.
[EX A]: How many members were in the National Assembly?
