Problem: Department store:

The first department store in the Philippines is the Hoskyn's Department Store of Hoskyn & Co. established in 1877 in Iloilo by the Englishman Henry Hoskyn, nephew of Nicholas Loney, the first British vice-consul in Iloilo. Some of the earliest department stores in the Philippines were located in Manila as early as 1898 with the opening of the American Bazaar, which was later named Beck's. During the course of the American occupation of the Philippines, many department stores were built throughout the city, many of which were located in Escolta. Heacock's, a luxury department store, was considered as the best department store in the Orient. Other department stores included Aguinaldo's, La Puerta del Sol, Estrella del Norte, and the Crystal Arcade, all of which were destroyed during the Battle of Manila in 1945. After the war, department stores were once again alive with the establishment of Shoemart (now SM), and Rustan's. Since the foundation of these companies in the 1950s, there are now more than one hundred department stores to date. At present, due to the huge success of shopping malls, department stores in the Philippines usually are anchor tenants within malls. SM Supermalls and Robinsons Malls are two of the country's most prominent mall chains, all of which has Department Store sections.

Problem: The term "high fidelity" was coined in the 1920s by some manufacturers of radio receivers and phonographs to differentiate their better-sounding products claimed as providing "perfect" sound reproduction. The term began to be used by some audio engineers and consumers through the 1930s and 1940s. After 1949 a variety of improvements in recording and playback technologies, especially stereo recordings, which became widely available in 1958, gave a boost to the "hi-fi" classification of products, leading to sales of individual components for the home such as amplifiers, loudspeakers, phonographs, and tape players. High Fidelity and Audio were two magazines that hi-fi consumers and engineers could read for reviews of playback equipment and recordings.

In 1888, the Italian administration launched its first development projects in the new colony. The Eritrean Railway was completed to Saati in 1888, and reached Asmara in the highlands in 1911.

Context and question: The BCG vaccine has limitations, and research to develop new TB vaccines is ongoing. A number of potential candidates are currently in phase I and II clinical trials. Two main approaches are being used to attempt to improve the efficacy of available vaccines. One approach involves adding a subunit vaccine to BCG, while the other strategy is attempting to create new and better live vaccines. MVA85A, an example of a subunit vaccine, currently in trials in South Africa, is based on a genetically modified vaccinia virus. Vaccines are hoped to play a significant role in treatment of both latent and active disease.
What candidate is in phase I and II?
Answer: unanswerable


Question: Digimon was first conceived as a virtual pet toy in the vein of Tamagotchis and, as such, took influence from Tamagotchis' cute and round designs. The small areas of the screens (16 by 16 pixels) meant that character designers had to create monsters whose forms would be easily recognizable. As such, many of the early Digimon—including Tyrannomon, the first one ever created—were based on dinosaurs. Many further designs were created by Kenji Watanabe, who was brought in to help with the "X-Antibody" creatures and art for the Digimon collectible card game. Watanabe was one influenced by American comics, which were beginning to gain popularity in Japan, and as such began to make his characters look stronger and "cool." The character creation process, however, has for most of the franchise's history been collaborative and reliant on conversation and brainstorming.
Is there an answer to this question: What was the screen size of the Digimon toy?

Answer: 16 by 16 pixels
