Problem: Miami:

Miami has a tropical monsoon climate (Köppen climate classification Am) with hot and humid summers and short, warm winters, with a marked drier season in the winter. Its sea-level elevation, coastal location, position just above the Tropic of Cancer, and proximity to the Gulf Stream shapes its climate. With January averaging 67.2 °F (19.6 °C), winter features mild to warm temperatures; cool air usually settles after the passage of a cold front, which produces much of the little amount of rainfall during the season. Lows occasionally fall below 50 °F (10 °C), but very rarely below 35 °F (2 °C). Highs generally range between 70–77 °F (21–25 °C).

In degrees Celsius, what temperature does Miami rarely see?

A: 2


Problem: Infrared:

Infrared radiation is used in industrial, scientific, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space, such as molecular clouds; detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.

What discipline uses infrared telescopes to see through molecular clouds?
---
A: Infrared astronomy


Problem: New Haven, Connecticut:

The city has many distinct neighborhoods. In addition to Downtown, centered on the central business district and the Green, are the following neighborhoods: the west central neighborhoods of Dixwell and Dwight; the southern neighborhoods of The Hill, historic water-front City Point (or Oyster Point), and the harborside district of Long Wharf; the western neighborhoods of Edgewood, West River, Westville, Amity, and West Rock-Westhills; East Rock, Cedar Hill, Prospect Hill, and Newhallville in the northern side of town; the east central neighborhoods of Mill River and Wooster Square, an Italian-American neighborhood; Fair Haven, an immigrant community located between the Mill and Quinnipiac rivers; Quinnipiac Meadows and Fair Haven Heights across the Quinnipiac River; and facing the eastern side of the harbor, The Annex and East Shore (or Morris Cove).

What east-central neighborhood in New Haven is home to a large number of Italian-Americans?
---
A: Wooster Square


Problem: Flowering plant:

Double fertilization refers to a process in which two sperm cells fertilize cells in the ovary. This process begins when a pollen grain adheres to the stigma of the pistil (female reproductive structure), germinates, and grows a long pollen tube. While this pollen tube is growing, a haploid generative cell travels down the tube behind the tube nucleus. The generative cell divides by mitosis to produce two haploid (n) sperm cells. As the pollen tube grows, it makes its way from the stigma, down the style and into the ovary. Here the pollen tube reaches the micropyle of the ovule and digests its way into one of the synergids, releasing its contents (which include the sperm cells). The synergid that the cells were released into degenerates and one sperm makes its way to fertilize the egg cell, producing a diploid (2n) zygote. The second sperm cell fuses with both central cell nuclei, producing a triploid (3n) cell. As the zygote develops into an embryo, the triploid cell develops into the endosperm, which serves as the embryo's food supply. The ovary now will develop into fruit and the ovule will develop into seed.

What begins the process of synergid?
