question:
To protect its seagoing interests and trade routes, Portugal established strategic garrisons in Goa (India), Malacca (East Indies), and Hormuz in the Persian Gulf. Portuguese explorers then embarked upon Macau (now Macao), the Congo, and various other parts of Africa, including the Sudan. The Portuguese policy was to avoid armed strife and to develop a trade empire, rather than to conquer nations. To this end it succeeded with relatively few blood-soaked episodes in its colonial history. Adventures abroad, however, proved disastrous during the second half of the 16th century. In 1557 the 14-year-old boy-king Sebastiao ascended the throne, the beginning of a calamitous reign that was to end at the battle of Alcacer-Quiber (Morocco) in pursuit of a vain crusade. Sebastiao's untimely demise, alongside some 18,000 ill-prepared, badly led followers, set the stage for a crisis of succession. For many years afterwards, legends and rumors bizarrely insisted that the king was still alive, and imposters turned up from time to time claiming the throne; those who were plausible enough to be deemed a threat were summarily executed. In fact, the only rightful claimant to the crown was the elderly Prince Henry. But after two years of alternating between the throne and his sickbed, he died, heirless. Surveying the situation and smelling an opportunity, Spain occupied the power vacuum, and Portugal's neighbor and long-time antagonist became its master. Spanish rule dictated Portugal's inadvertent involvement in Spain's ongoing wars. In 1587 a squadron of British ships commanded by Francis Drake attacked the Algarve (now a "legitimate target" as Spanish territory) and sacked Sagres, thus depriving the world of the relics of Henry the Navigator. Nine years later Faro was torched. The 1386 Treaty of Windsor, by which Britain and Portugal had pledged eternal friendship, seemed a distant memory. Portugal's empire was gradually eroded, and many of its trading posts (with the notable exception of Brazil) were picked off by the British and Dutch. Finally, after 60 years of Spanish rule, Portuguese noblemen (aided by the French, then at war with Spain) organized a palace coup and restored independence. The Great Disaster Portugal's greatest misfortune struck on All Saint's Day, 1 November 1755. <sep>Why was Portugal's conquest of many ports said to not be "blood-soaked"?<sep>They made the survivors slaves
answer:
No

question:
Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it. <sep>How do magnets produce change?<sep>They produce change just like humans do
answer:
No

question:
Thursday, and Mr. Strong arrived with the inevitableness of dreaded events. Bambi felt convinced that his coming meant the premature death of her new-born career, so, naturally, she was prepared for grief. An element of amusement was added, however, by Jarvis's astonishing behaviour. Ever since the first mention of Mr. Strong's name he had shown unmistakable signs of dislike for that gentleman. 'It was the most remarkable revelation of his strange character. Having totally ignored Bambi himself, it distressed him to think of any other man being attracted by her. His references to Mr. Strong's coming were many and satirical. This display of manly inconsistency was nuts and ale to Bambi. She wondered how much Mr. Strong would play up, and she decided to give Jarvis Jocelyn an uncomfortable hour. She herself was an adept in amatory science, but she was a trifle unsure of Mr. Strong. However, she remembered a certain twinkle in his eye that augured well. Because it was necessary to enlighten him as to the situation in advance, she arrayed herself most carefully to go and meet him. She encountered Jarvis on the stairs. He inspected her charming self, in a frock the colour of spring green leaves, topped by a crocus-coloured hat, like a flower. She deliberately pranced before him. <sep>What day did Mr. Strong arrive and who dreaded the encounter?<sep>Mr. Strong arrived with the inevitableness of dreaded events

No
