Problem: Botany:

The hypothesis that plant growth and development is coordinated by plant hormones or plant growth regulators first emerged in the late 19th century. Darwin experimented on the movements of plant shoots and roots towards light and gravity, and concluded "It is hardly an exaggeration to say that the tip of the radicle . . acts like the brain of one of the lower animals . . directing the several movements". About the same time, the role of auxins (from the Greek auxein, to grow) in control of plant growth was first outlined by the Dutch scientist Frits Went. The first known auxin, indole-3-acetic acid (IAA), which promotes cell growth, was only isolated from plants about 50 years later. This compound mediates the tropic responses of shoots and roots towards light and gravity. The finding in 1939 that plant callus could be maintained in culture containing IAA, followed by the observation in 1947 that it could be induced to form roots and shoots by controlling the concentration of growth hormones were key steps in the development of plant biotechnology and genetic modification.

When was the theory of plant hormones introduced?

Problem: High-definition television:

Since the formal adoption of digital video broadcasting's (DVB) widescreen HDTV transmission modes in the early 2000s; the 525-line NTSC (and PAL-M) systems, as well as the European 625-line PAL and SECAM systems, are now regarded as standard definition television systems.

In addition to the NTSC system, what 525-line system is considered a high definition television system?
---
A: unanswerable


Problem: San Diego:

The San Diego Surf of the American Basketball Association is located in the city. The annual Farmers Insurance Open golf tournament (formerly the Buick Invitational) on the PGA Tour occurs at Torrey Pines Golf Course. This course was also the site of the 2008 U.S. Open Golf Championship. The San Diego Yacht Club hosted the America's Cup yacht races three times during the period 1988 to 1995. The amateur beach sport Over-the-line was invented in San Diego, and the annual world Over-the-line championships are held at Mission Bay every year.

What golf course hosts the Farmers Insurance Open?
---
A: Torrey Pines Golf Course


Problem: Alfred North Whitehead:

Whitehead pointed to the limitations of language as one of the main culprits in maintaining a materialistic way of thinking, and acknowledged that it may be difficult to ever wholly move past such ideas in everyday speech. After all, each moment of each person's life can hardly be given a different proper name, and it is easy and convenient to think of people and objects as remaining fundamentally the same things, rather than constantly keeping in mind that each thing is a different thing from what it was a moment ago. Yet the limitations of everyday living and everyday speech should not prevent people from realizing that "material substances" or "essences" are a convenient generalized description of a continuum of particular, concrete processes. No one questions that a ten-year-old person is quite different by the time he or she turns thirty years old, and in many ways is not the same person at all; Whitehead points out that it is not philosophically or ontologically sound to think that a person is the same from one second to the next.

What did Whitehead state about the belief that a person is exactly the same from moment to moment?

A:
it is not philosophically or ontologically sound
