You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").

[Q]: Paragraph- Sent 1: For much of the world, the Algarve is synonymous with Portugal, yet the Portuguese will tell you the exact opposite: the region has little in common with the rest of the country.
Sent 2: The southern stretch of coast is more reminiscent of a North African landscape than a European one.
Sent 3: It has no cosmopolitan cities, like Lisbon and Porto, which are farther north.
Sent 4: Most of Portugal is known for quaint towns, medieval castles, and grand palaces.
Sent 5: The Algarve is more recognizable for impenetrable blocks of tourist apartments, hotels, and meticulously manicured golf courses.
Sent 6: And beaches.
Sent 7: Think Algarve and the mind pictures long, glorious stretches of golden sands, secluded coves framed by odd ochre-colored rock formations, and deep green waters.
Sent 8: With about 160 km (100 miles) of coastline, Portugal's southern province is one of Europe's premier beach destinations.
Sent 9: The occasionally chilly ocean is the Atlantic, but the Algarve has a sultry Mediterranean feel.
Sent 10: Its consistent climate is the best in Portugal, and one of the kindest in the world: more than 250 days of sunshine a yearmore than almost any other international resort area.
Sent 11: The moderating effect of the Gulf Stream produces a fresh springtime breeze throughout winter, and in late January and February, white almond blossoms blanket the fields.
Sent 12: In summer the heat is intense but rarely unbearable, and regardless, beautiful beaches and innumerable pools are always just a dive away.
Sent 13: Magnificent year-round weather has made the Algarve a huge destination for sporting vacations.
Sent 14: Superb golf facilities aboundseveral with tees dramatically clinging to cliffs and fairways just skirting the edge of the oceanand horseback riding, tennis, big-game fishing, sailing, and windsurfing are immensely popular.
Sent 15: Sports, beaches and hospitable weathernot to mention easily organized package vacationsare surely the reasons the Algarve receives as many visitors as the rest of Portugal in its entirety.
Sent 16: But it's not just international tourists that descend on the Algarve; many Portuguese from Lisbon and elsewhere in the north have holiday homes and spend their summer vacations here.
Sent 17: The coast is neatly divided into the rugged Barlavento to the west and the flat beauty of Sotavento to the east.
Sent 18: West is where you'll find the famous orange cliffs and surreal eroded rock stacks.

[Q]: Paragraph- Sent 1: (CNN) -- Guatemala's government has declared a state of siege and sent hundreds of troops to a northern province where officials say a Mexican drug gang is overtaking towns and threatening residents.
Sent 2: President Alvaro Colom announced the 30-day emergency rule in Alta Verapaz on Sunday.
Sent 3: The rule allows the military to order anyone suspected of conspiring against the government to be arrested and imprisoned without a warrant, the state-run AGN news agency said.
Sent 4: "Starting today, combined forces will retake the streets of Alta Verapaz," a government statement released Sunday morning said.
Sent 5: Government data shows cells of the drug gang known as Los Zetas are in the area to protect drug trafficking paths between Honduras and Mexico, "intimidating the population with their heavy weapons and threatening farmers to give up their land for criminal activities," AGN reported.
Sent 6: The state of siege also allows the government to place greater restrictions on public gatherings, travel visas and gun licenses, among other things, according to AGN.
Sent 7: "The population should be calm.
Sent 8: What we are doing is not intended to persecute honest, working people," Interior Minister Carlos Menocal told reporters.

Sent 10: In an interview with CNN en Espanol last month, Menocal said his country needed more help from the United States to combat cartels, which were increasingly carving out new drug transport paths.
Sent 11: "In the end, the large majority of drugs travel through Central America, and the assignment of resources or the financial support of the United States government is not the same as Colombia and Mexico receive," he said.
Sent 12: Menocal said clashes between authorities and Los Zetas had notably increased.
