Q: A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables laid beginning in the 1850s carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fiber technology to carry digital data, which includes telephone, Internet and private data traffic.
Can we conclude that are there fiber optic cables under the ocean?
A: yes

Q: The U.S. Passport Card is the de facto national identification card of the United States and a limited travel document issued by the federal government of the United States in the size of a credit card. Like a passport book, the passport card is only issued to U.S. citizens and U.S. nationals exclusively by the U.S. Department of State and is compliant to the standards for identity documents set by the REAL ID Act and can be used as proof of U.S. citizenship. The passport card's intended primary purpose is for identification and to allow cardholders to travel by domestic air flights within the United States and to enter or exit the United States via land and sea between member states of the Western Hemisphere Travel Initiative (WHTI). However, the passport card cannot be used for international air travel.
Can we conclude that can a passport card be used as id?
A: yes

Q: In the United States of America, driver's licenses are issued by each individual state, territory, and the federal district rather than by the federal government because of the concept of federalism. Drivers are normally required to obtain a license from their state of residence and all states recognize each other's licenses for non-residents subject to normal age requirements. A state may also suspend an individual's driving privilege within its borders for traffic violations. Many states share a common system of license classes, with some exceptions, e.g. commercial license classes are standardized by federal regulation at 49 C.F.R. 383.
Can we conclude that does a driver's license work in every state?
A: yes
