The following day, the armies of four Arab countriesEgypt, Syria, Transjordan and Iraqentered what had been British Mandatory Palestine, launching the 1948 ArabIsraeli War; Contingents from Yemen, Morocco, Saudi Arabia and Sudan joined the war. The apparent purpose of the invasion was to prevent the establishment of the Jewish state at inception, and some Arab leaders talked about driving the Jews into the sea. According to Benny Morris, Jews felt that the invading Arab armies aimed to slaughter the Jews. The Arab league stated that the invasion was to restore law and order and to prevent further bloodshed.
What were the invading Arab armies aim?
****
The answer: slaughter the Jews

Problem: Please answer a question about the following article about Gothic architecture:
The pointed arch, one of the defining attributes of Gothic, was earlier incorporated into Islamic architecture following the Islamic conquests of Roman Syria and the Sassanid Empire in the Seventh Century. The pointed arch and its precursors had been employed in Late Roman and Sassanian architecture; within the Roman context, evidenced in early church building in Syria and occasional secular structures, like the Roman Karamagara Bridge; in Sassanid architecture, in the parabolic and pointed arches employed in palace and sacred construction.
The Roman Karamagara Bridge is an example of what type of structure?
A: secular structures

The first Roman republican wars were wars of both expansion and defence, aimed at protecting Rome itself from neighbouring cities and nations and establishing its territory in the region. Initially, Rome's immediate neighbours were either Latin towns and villages, or else tribal Sabines from the Apennine hills beyond. One by one Rome defeated both the persistent Sabines and the local cities, both those under Etruscan control and those that had cast off their Etruscan rulers. Rome defeated Latin cities in the Battle of Lake Regillus in 496 BC, the Battle of Mons Algidus in 458 BC, the Battle of Corbione in 446 BC, the Battle of Aricia, and especially the Battle of the Cremera in 477 BC wherein it fought against the most important Etruscan city of Veii.

What Roman battle took place in the year 446 BC?
Answer: the Battle of Corbione

Problem: The original USB 1.0 specification, which was introduced in January 1996, defined data transfer rates of 1.5 Mbit/s "Low Speed" and 12 Mbit/s "Full Speed". Microsoft Windows 95, OSR 2.1 provided OEM support for the devices. The first widely used version of USB was 1.1, which was released in September 1998. The 12 Mbit/s data rate was intended for higher-speed devices such as disk drives, and the lower 1.5 Mbit/s rate for low data rate devices such as joysticks. Apple Inc.'s iMac was the first mainstream product with USB and the iMac's success popularized USB itself. Following Apple's design decision to remove all legacy ports from the iMac, many PC manufacturers began building legacy-free PCs, which led to the broader PC market using USB as a standard.
1.1 was the first widely used version of what?
The answer is the following: USB

Very low sounds are also produced in various species of Coleoptera, Hymenoptera, Lepidoptera, Mantodea and Neuroptera. These low sounds are simply the sounds made by the insect's movement. Through microscopic stridulatory structures located on the insect's muscles and joints, the normal sounds of the insect moving are amplified and can be used to warn or communicate with other insects. Most sound-making insects also have tympanal organs that can perceive airborne sounds. Some species in Hemiptera, such as the corixids (water boatmen), are known to communicate via underwater sounds. Most insects are also able to sense vibrations transmitted through surfaces.
What sound volume is produced by Coleoptera?
low

Here is a question about this article: Large brushes are desired for a larger brush contact area to maximize motor output, but small brushes are desired for low mass to maximize the speed at which the motor can run without the brushes excessively bouncing and sparking. (Small brushes are also desirable for lower cost.) Stiffer brush springs can also be used to make brushes of a given mass work at a higher speed, but at the cost of greater friction losses (lower efficiency) and accelerated brush and commutator wear. Therefore, DC motor brush design entails a trade-off between output power, speed, and efficiency/wear.
What is the answer to this question: Besides wear, what is a downside of stiff brush springs?
****
So...
lower efficiency
