Input: Printed circuit board
Each trace consists of a flat, narrow part of the copper foil that remains after etching. The resistance, determined by width and thickness, of the traces must be sufficiently low for the current the conductor will carry. Power and ground traces may need to be wider than signal traces. In a multi-layer board one entire layer may be mostly solid copper to act as a ground plane for shielding and power return. For microwave circuits, transmission lines can be laid out in the form of stripline and microstrip with carefully controlled dimensions to assure a consistent impedance. In radio-frequency and fast switching circuits the inductance and capacitance of the printed circuit board conductors become significant circuit elements, usually undesired; but they can be used as a deliberate part of the circuit design, obviating the need for additional discrete components.

What type of trace is often narrower than a ground trace?
Output: signal

Input: Article: The exonym Armenia is attested in the Old Persian Behistun Inscription (515 BC) as Armina ( ). The ancient Greek terms (Armenia) and (Armenioi, "Armenians") are first mentioned by Hecataeus of Miletus (c. 550 BC c. 476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians. According to the histories of both Moses of Chorene and Michael Chamchian, Armenia derives from the name of Aram, a lineal descendant of Hayk.

Now answer this question: When did Xenophon visit Armenia?

Output: 401 BC

Article: Guinea-Bissau is warm all year around and there is little temperature fluctuation; it averages 26.3 C (79.3 F). The average rainfall for Bissau is 2,024 millimetres (79.7 in) although this is almost entirely accounted for during the rainy season which falls between June and September/October. From December through April, the country experiences drought.

Question: When is the rainy season in Guinea-Bissau?
Ans: between June and September/October

Here is a question about this article: Panels are individual images containing a segment of action, often surrounded by a border. Prime moments in a narrative are broken down into panels via a process called encapsulation. The reader puts the pieces together via the process of closure by using background knowledge and an understanding of panel relations to combine panels mentally into events. The size, shape, and arrangement of panels each affect the timing and pacing of the narrative. The contents of a panel may be asynchronous, with events depicted in the same image not necessarily occurring at the same time.
What is the answer to this question: Timing and pace of comics is made by adjusting size, shape and what of panels?

So... arrangement

In the First World War, Devonport was the headquarters of Western Approaches Command until 1941 and Sunderland flying boats were operated by the Royal Australian Air Force. It was an important embarkation point for US troops for D-Day. The city was heavily bombed by the Luftwaffe, in a series of 59 raids known as the Plymouth Blitz. Although the dockyards were the principal targets, much of the city centre and over 3,700 houses were completely destroyed and more than 1,000 civilians lost their lives. This was largely due to Plymouth's status as a major port Charles Church was hit by incendiary bombs and partially destroyed in 1941 during the Blitz, but has not been demolished, as it is now an official permanent monument to the bombing of Plymouth during World War II.
How many civilian deaths occurred as a result of the Plymouth Blitz?
****
The answer: more than 1,000

In early 2001, Apple began shipping computers with CD-RW drives and emphasized the Mac's ability to play DVDs by including DVD-ROM and DVD-RAM drives as standard. Steve Jobs admitted that Apple had been "late to the party" on writable CD technology, but felt that Macs could become a "digital hub" that linked and enabled an "emerging digital lifestyle". Apple would later introduce an update to its iTunes music player software that enabled it to burn CDs, along with a controversial "Rip, Mix, Burn" advertising campaign that some felt encouraged media piracy. This accompanied the release of the iPod, Apple's first successful handheld device. Apple continued to launch products, such as the unsuccessful Power Mac G4 Cube, the education-oriented eMac, and the titanium (and later aluminium) PowerBook G4 laptop for professionals.
What is the name of one of Apple's unsuccessful products?
****
The answer:
Power Mac G4 Cube
