Problem: The history of mobile telephony in Brazil began on 30 December 1990, when the Cellular Mobile System began operating in the city of Rio de Janeiro, with a capacity for 10,000 terminals. At that time, according to Anatel (the national telecommunications agency), there were 667 devices in the country. The number of devices rose to 6,700 in the next year, to 30,000 in 1992. In November 2007 3G services were launched, and increased rapidly to almost 90% of the population in 2012 and the agreements signed as part of the auction specify a 3G coverage obligation of 100% of population by 2019. After the auction that took place in June 2012, LTE tests were undertaken in several cities, tourist locations and international conference venues. The first LTE-compatible devices became available in the local market and LTE services was commercially launched in 2013. Under the 4G licence terms, operators were required to have commercial networks in all twelve state capitals which are acting as host cities for the 2014 FIFA World Cup.

Problem: When Halsey turned TF34 southwards at 11:15, he detached a task group of four of its cruisers and nine of its destroyers under Rear Admiral DuBose, and reassigned this group to TF38. At 14:15, Mitscher ordered DuBose to pursue the remnants of the Japanese Northern Force. His cruisers finished off the light carrier Chiyoda at around 17:00, and at 20:59 his ships sank the destroyer Hatsuzuki after a very stubborn fight. When Admiral Ozawa learned of the deployment of DuBose's relatively weak task group, he ordered battleships Ise and Hyuga to turn southwards and attack it, but they failed to locate DuBose's group, which they heavily outgunned. Halsey's withdrawal of all six of Lee's battleships in his attempt to assist Seventh Fleet had now rendered TF38 vulnerable to a surface counterattack by the decoy Northern Force. At about 23:10, the American submarine Jallao torpedoed and sank the light cruiser Tama of Ozawa's force. This was the last act of the Battle of Cape Engano, andapart from some final air strikes on the retreating Japanese forces on 26 Octoberthe conclusion of the Battle for Leyte Gulf.

Did Rear Admiral DuBose have more cruisers or more destroyers?
Answer: destroyers
