The problem: Answer a question about this article:
For horizontal propagation between transmitting and receiving antennas situated near the ground reasonably far from each other, the distances traveled by tne direct and reflected rays are nearly the same. There is almost no relative phase shift. If the emission is polarized vertically, the two fields (direct and reflected) add and there is maximum of received signal. If the signal is polarized horizontally, the two signals subtract and the received signal is largely cancelled. The vertical plane radiation patterns are shown in the image at right. With vertical polarization there is always a maximum for θ=0, horizontal propagation (left pattern). For horizontal polarization, there is cancellation at that angle. Note that the above formulae and these plots assume the ground as a perfect conductor. These plots of the radiation pattern correspond to a distance between the antenna and its image of 2.5λ. As the antenna height is increased, the number of lobes increases as well.
What is also increased along with the antenna's height?
****
The answer: lobes

The Desert National Park in Jaisalmer is spread over an area of 3,162 square kilometres (1,221 sq mi), is an excellent example of the ecosystem of the Thar Desert and its diverse fauna. Seashells and massive fossilised tree trunks in this park record the geological history of the desert. The region is a haven for migratory and resident birds of the desert. One can see many eagles, harriers, falcons, buzzards, kestrels and vultures. Short-toed eagles (Circaetus gallicus), tawny eagles (Aquila rapax), spotted eagles (Aquila clanga), laggar falcons (Falco jugger) and kestrels are the commonest of these.
What is another name for a laggar falcon?
****
The answer: Falco jugger


The problem: Answer a question about this article:
SVCD has two-thirds the resolution of DVD, and over 2.7 times the resolution of VCD. One CD-R disc can hold up to 60 minutes of standard quality SVCD-format video. While no specific limit on SVCD video length is mandated by the specification, one must lower the video bit rate, and therefore quality, to accommodate very long videos. It is usually difficult to fit much more than 100 minutes of video onto one SVCD without incurring significant quality loss, and many hardware players are unable to play video with an instantaneous bit rate lower than 300 to 600 kilobits per second.
Which has better resolution, a VCD or SVCD?
****
The answer: SVCD

 Greece: On March 24, 2008, the Olympic Flame was ignited at Olympia, Greece, site of the ancient Olympic Games. The actress Maria Nafpliotou, in the role of a High Priestess, ignited the torch of the first torchbearer, a silver medalist of the 2004 Summer Olympics in taekwondo Alexandros Nikolaidis from Greece, who handed the flame over to the second torchbearer, Olympic champion in women's breaststroke Luo Xuejuan from China. Following the recent unrest in Tibet, three members of Reporters Without Borders, including Robert Ménard, breached security and attempted to disrupt a speech by Liu Qi, the head of Beijing's Olympic organising committee during the torch lighting ceremony in Olympia, Greece. The People's Republic of China called this a "disgraceful" attempt to sabotage the Olympics. On March 30, 2008 in Athens, during ceremonies marking the handing over of the torch from Greek officials to organizers of the Beijing games, demonstrators shouted 'Free Tibet' and unfurled banners; some 10 of the 15 protesters were taken into police detention. After the hand-off, protests continued internationally, with particularly violent confrontations with police in Nepal.
On what date did the Olympic Flame get lit?
****
The answer:
March 24, 2008
