During the Middle Ages, societies were based on military relationships, as landowners formed their own foot armies into which they drafted their tenants and hired hands. The infantry that fought its way forward against the opposition engaged in heavy ground battles that proved costly in the ratio of losses to wins. These soldiers carried darts, javelins, and slings to be used before closing ranks with the enemy, although their swords and halberds delivered crushing blows on contact. Such armed forces were active for limited periods of time and had a predominantly defensive function, displayed in hand-to-hand combat.
            Because this sporadic and untrained organization was ineffective, the ruling classes began to hire mercenaries who were generously compensated for their tasks and subject to contractual terms of agreement. The greatest idiosyncrasy of a hired military force was that the troops sometimes deserted their employers if they could bank on a higher remuneration from the opposition.  The Swiss pikemen became the best-known mercenaries of the late Middle Ages. In the 1300s, they practically invented a crude body armor of leather and quilted layered head gear with nose and skull plates, ornamented with crests. Their tower shields proved indispensable against a shower of arrows, and their helmets progressed from cone cups to visors hinged at the temples. As their notoriety increased, so did their wages, and eventually they were rounded into military companies that later grew into the basic units in almost all armies. During the same period, the first full-size army of professional soldiers emerged in the Ottoman Empire. What set these troops apart from other contemporary armies was that these soldiers remained on duty in peacetime.
            Companies of mercenaries were employed on a permanent basis in 1445, when King Charles VII created a regular military organization, complete with a designated hierarchy.. Gunpowder accelerated the emergence of military tactics  and strategy that ultimately affected the conceptualization of war on a broad scale. Cannons further widened the gap between the attacking and the defending lineups, and undermined the exclusivity of contact battles.
The phrase “these troops” refers to
A.the Swiss pikemen  
B.military companies
C.almost all armies  
D.Ottoman soldiers

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
The Forbidden City is the former imperial palace in the center of Beijing, China. Construction began in 1406, and the emperor's court officially moved in by 1420. The Forbidden City got its name because most people were barred from entering the 72-hectare site, surrounded by walls. Even government officials and the imperial family were permitted only limited access. Only the emperor could enter any section at will.
The architecture of the Forbidden City conforms rigidly to traditional Chinese principles. All buildings within the walls follow a north-south line and the most important ones face south to honor the sun. The designers arranged the other buildings, and the ceremonial spaces between them, to impress all visitors with the great power of the Emperor, while reinforcing the insignificance of the individual. This architectural concept was carried out to the smallest detail. For example, the importance of a building was determined not only by its height or width but also by the style of its roof and the quantity of statuettes placed on the roof’s ridges.
In recognition of the importance of its unparalleled architecture, UNESCO added the palace to its World Heritage List in 1987. Today, visitors from all over the world do not wait for an imperial invitation to walk about this palace, now a museum of imperial art.
One of the most impressive landmarks of the Forbidden City is the Meridian Gate, the formal entrance to the southern side of the Forbidden City. The gate, with its auxiliary wings on either side of the entryway, is 38 meters high at its roof ridge. When you stand in front of this majestic structure, you understand how awed people felt when they stood there listening to imperial proclamations.
As you walk through the gate, you come into a large courtyard, 140 meters long and 210 meters wide. Running through the courtyard is the Golden River, which is crossed by five parallel white marble bridges. These bridges lead to the Gate of Supreme Harmony, which, in turn, leads to the heart of the Forbidden City. At the northernmost end of the Forbidden City is the Imperial Garden, which is totally different from the rest of the compound. Instead of rigid formality, you see a seemingly spontaneous arrangement of trees, fishponds, flowerbeds, and sculpture. Here is the place of relaxation for the emperor.
Which word or phrase is closest in meaning to the word "spontaneous"?
A.Without thinking
B.Unique      
C.Without planning   
D.Strange
