Problem: The MexicanAmerican War, also known as the Mexican War and in Mexico the American intervention in Mexico, was an armed conflict between the United States of America and the United Mexican States (Mexico) from 1846 to 1848. It followed in the wake of the 1845 American annexation of the independent Republic of Texas, which Mexico still considered its northeastern province and a part of its territory after its "de facto" secession in the 1836 Texas Revolution a decade earlier.

After its Treaty of Cordoba with obtaining independence in 1821, from the Kingdom of Spain and its Spanish Empire as New Spain for the past 300 years, and a brief experiment with a monarchy government, Mexico became a republic in 1824. It was characterized by considerable instability, leaving it ill-prepared for international conflict only two decades later when war broke out in 1846. Native American raids in Mexico's sparsely settled north in the decades preceding the war prompted the Mexican government to sponsor migration from the U.S.A. on its northeast border (since 1803 with the Louisiana Purchase from the French Empire (France) of Emperor Napoleon I) to the Mexican province of Texas to create a buffer. However, the newly-named "Texians" revolted against the Mexican government of President / dictator Antonio Lopez de Santa Ana, who had usurped the Mexican constitution of 1824, in the subsequent 1836 Texas Revolution, creating a republic not recognized by Mexico, which still claimed it as part of its national territory. In 1845, the Texan Republic agreed to an offer of annexation by the U.S. Congress, and became the 28th state in the Union on December 29 that year.

Problem: There once was a beautiful, brown puppy who loved her life. Her name was Tori. Every morning, Patty brushed out her fur and feeds Tori her favorite breakfast. One Tuesday morning, Patty had an early errand and forgot all about Tori. Tori was sad, but chose to make the best of it, and leaped out of her doggy door to play in her backyard outside. As she was playing with her favorite ball, Tori saw an opening in the fence. Excited, she ran over to the fence and squeezed out. She had never been on the street by herself before. Tori ran down the sidewalk, and happily barked at all the other dogs she passed. She loved to wag her tail in the summer breeze and was having a great time.

All of a sudden, Tori was picked up by Ben and Mike, and thrown into a truck. She was lost and confused. Poor Tori didn't know what to do! The truck pulled up to a building with a big sign that said "Animal Control". Tori knew this was the place that people keep animals who are lost on the street. Once the workers took her inside, they put her into a cage. She was scared that Patty wouldn't know where to find her, but she knew Patty's phone number was on her collar. She barked and barked to get the worker's attention, but no one seemed to pay her any attention.

After two long hours, a tall man, named Joe, opened up her cage and looked at the charm on her collar. He smiled at Tori and gave her a pat on the head. Patty was there quickly, and gave Tori a big hug. She was so happy to see her puppy again.

Tori learned to never escape the backyard again and lived happily ever after with Patty.
1. What type of animal is Tori?
2. Who generally takes care of her?
Answer: 1. puppy
2. Patty

Problem: Wi-Fi or WiFi () is a technology for wireless local area networking with devices based on the IEEE 802.11 standards. "Wi-Fi" is a trademark of the Wi-Fi Alliance, which restricts the use of the term "Wi-Fi Certified" to products that successfully complete interoperability certification testing.

Devices that can use Wi-Fi technology include personal computers, video-game consoles, phones and tablets, digital cameras, smart TVs, digital audio players and modern printers. Wi-Fi compatible devices can connect to the Internet via a WLAN and a wireless access point. Such an access point (or hotspot) has a range of about indoors and a greater range outdoors. Hotspot coverage can be as small as a single room with walls that block radio waves, or as large as many square kilometres achieved by using multiple overlapping access points.

Wi-Fi most commonly uses the UHF and SHF ISM radio bands. Having no physical connections, it is more vulnerable to attack than wired connections, such as twisted pair.

In 1971, ALOHAnet connected the Hawaiian Islands with a UHF wireless packet network. ALOHAnet and the ALOHA protocol were early forerunners to Ethernet, and later the IEEE 802.11 protocols, respectively.

A 1985 ruling by the U.S. Federal Communications Commission released the ISM band for unlicensed use. These frequency bands are the same ones used by equipment such as microwave ovens and are subject to interference.
