[EX Q]: New Horizons: Exhausted after the Civil War, Spain remained on the sidelines during World War II and began to recover economically under the oppressive, law-and-order regime of Franco. There had been a foretaste of elite foreign tourism in the 1920s, but it was the late 1950s when the rest of Europe began sun-seeking pilgrimages to Spain. Tourism exploded into an annual southern migration, transforming the Spanish economy, landscape, and society. Eager to capitalize, the country poured its soul into mass tourism, which triggered a rash of indiscriminate building on the southern and eastern coastlines, with scant regard for tradition or aesthetics. But after so many years closed off from the rest of Europe, of equal significance was the injection of foreign influences into Franco's once hermetically sealed Spain. Mallorca and Menorca in particular saw explosive growth in tourism; by the 1970s, the Balearics were one of Europe's most popular holiday destinations. Franco named as his successor the grandson of Alfonso XIII, who was enthroned as King Juan Carlos I when the dictator died in 1975. To the dismay of Franco diehards, the king brilliantly managed the transition to democracy, then stood back to allow it full rein, even intervening during a brief attempt at a military coup. After many years of repression, new freedoms and autonomy were granted to Spanish regions, including the Balearics, and their languages and cultures enjoyed a long-desired renaissance. More a part of Europe than ever before, Spain joined the European Community (now European Union) in 1986, giving further boost to a booming economy. The tourist industry continued to expand, and though it became one of the top two income earners in Spain, a realization that unrestricted mass tourism was leading to damaging long-term consequences also began to grow. By the late 1990s, a new emphasis on quality and, especially in the Balearics, on safeguarding the environment had finally taken roottoo late for many environmentalists, but hopefully still in time to preserve much of the natural beauty and unique character of the Las Islas Baleares. <sep>Why was Spain so isolated and what event happened that allowed Mallorca and Menorca to see explosions in tourism?<sep>Spain was surrounded by enemies
[EX A]: No

[EX Q]: From a human point of view, a habitat is where you live. It might be your city, town, or neighborhood. Your habitat can be altered. Most people move a few times in their lives. But a plant cannot move. An animal may not be suited to live in another area. A habitat is the natural home or environment of an organism. Humans often destroy the habitats of other organisms. The loss of habitat can cause the extinction of species. Extinction is when a species disappears forever. Once a species is extinct, it can never be brought back. Humans cause habitat destruction in many ways. There are two common ways this happens. Land may be cleared. Another way is when an animal or plant is brought to an area where it does not belong. <sep>Once a species is extinct, can it be brought back?<sep>no, it is gone forever.
[EX A]: Yes

[EX Q]: Relying on an animal to come by is risky. A flower may have to wait a long time for the right animals to come by. What if one never passes close enough to the flower? Hoping the wind will blow is also risky for a plant. What if the wind does not blow? What if the blowing pollen does not land on another flower? The wind could even blow the pollen over the ocean where it is wasted. Giving free nectar is costly. It is not a good use of the plants energy. A plant uses a lot of energy to produce nectar. Some animals may just drink the nectar. They may not carry off any pollen in return. To improve their chances, plants evolved special traits. For example, they developed ways to hide their nectar. Only certain animals were able to get at the plants hidden nectar. These specific animals might be more likely to visit only flowers of the same species. This was also a benefit for some animals. Animals also evolved special traits to get to the nectar. <sep>What is risky for a plant with its nectar?<sep>Relying on an animal to come by
[EX A]:
Yes
