Problem: Please answer a question about the following article about Asphalt:
The word asphalt is derived from the late Middle English, in turn from French asphalte, based on Late Latin asphalton, asphaltum, which is the latinisation of the Greek (asphaltos, asphalton), a word meaning "asphalt/bitumen/pitch", which perhaps derives from -, "without" and (sfallo), "make fall". Note that in French, the term asphalte is used for naturally occurring bitumen-soaked limestone deposits, and for specialised manufactured products with fewer voids or greater bitumen content than the "asphaltic concrete" used to pave roads. It is a significant fact that the first use of asphalt by the ancients was in the nature of a cement for securing or joining together various objects, and it thus seems likely that the name itself was expressive of this application. Specifically Herodotus mentioned that bitumen was brought to Babylon to build its gigantic fortification wall. From the Greek, the word passed into late Latin, and thence into French (asphalte) and English ("asphaltum" and "asphalt").
What is the last origination of the word asphalt?
A: late Middle English
Problem: Please answer a question about the following article about Light-emitting diode:
Quantum dots (QD) are semiconductor nanocrystals that possess unique optical properties. Their emission color can be tuned from the visible throughout the infrared spectrum. This allows quantum dot LEDs to create almost any color on the CIE diagram. This provides more color options and better color rendering than white LEDs since the emission spectrum is much narrower, characteristic of quantum confined states. There are two types of schemes for QD excitation. One uses photo excitation with a primary light source LED (typically blue or UV LEDs are used). The other is direct electrical excitation first demonstrated by Alivisatos et al.
The narrowing of the emission spectrum in Quantum Dot LEDs allows them to do what?
A: better color rendering
Problem: Please answer a question about the following article about Transistor:
In a FET, the drain-to-source current flows via a conducting channel that connects the source region to the drain region. The conductivity is varied by the electric field that is produced when a voltage is applied between the gate and source terminals; hence the current flowing between the drain and source is controlled by the voltage applied between the gate and source. As the gatesource voltage (VGS) is increased, the drainsource current (IDS) increases exponentially for VGS below threshold, and then at a roughly quadratic rate (IGS (VGS VT)2) (where VT is the threshold voltage at which drain current begins) in the "space-charge-limited" region above threshold. A quadratic behavior is not observed in modern devices, for example, at the 65 nm technology node.
What determines the conductivity in a FET?
A: electric field that is produced when a voltage is applied between the gate and source terminals
Problem: Please answer a question about the following article about Dwight D. Eisenhower:
As the 1954 congressional elections approached, and it became evident that the Republicans were in danger of losing their thin majority in both houses, Eisenhower was among those blaming the Old Guard for the losses, and took up the charge to stop suspected efforts by the right wing to take control of the GOP. Eisenhower then articulated his position as a moderate, progressive Republican: "I have just one purpose ... and that is to build up a strong progressive Republican Party in this country. If the right wing wants a fight, they are going to get it ... before I end up, either this Republican Party will reflect progressivism or I won't be with them anymore."
What wing of the GOP was Eisenhower opposed to?
A:
right
