Problem: Detroit:

Detroit has four border crossings: the Ambassador Bridge and the Detroit–Windsor Tunnel provide motor vehicle thoroughfares, with the Michigan Central Railway Tunnel providing railroad access to and from Canada. The fourth border crossing is the Detroit–Windsor Truck Ferry, located near the Windsor Salt Mine and Zug Island. Near Zug Island, the southwest part of the city was developed over a 1,500-acre (610 ha) salt mine that is 1,100 feet (340 m) below the surface. The Detroit Salt Company mine has over 100 miles (160 km) of roads within.

How many routes to Canada does Detroit have?

A: four


Problem: Predation:

Social predation offers the possibility of predators to kill creatures larger than those that members of the species could overpower singly. Lions, hyenas, wolves, dholes, African wild dogs, and piranhas can kill large herbivores that single animals of the same species usually don't dispatch. Social predation allows some animals to organize hunts of creatures that would easily escape a single predator; thus chimpanzees can prey upon colobus monkeys, and Harris's hawks can cut off all possible escapes for a doomed rabbit. Extreme specialization of roles is evident in some hunting that requires co-operation between predators of very different species: humans with the aid of falcons or dogs, or fishing with cormorants. Social predation is often very complex behavior, and not all social creatures (for example, domestic cats) perform it. Even without complex intelligence but instinct alone, some ant species can destroy much larger creatures.

What are some species that use social predation to prey on animals much larger than themselves?
---
A: Lions, hyenas, wolves, dholes, African wild dogs, and piranhas


Problem: Pharmaceutical industry:

Often, large multinational corporations exhibit vertical integration, participating in a broad range of drug discovery and development, manufacturing and quality control, marketing, sales, and distribution. Smaller organizations, on the other hand, often focus on a specific aspect such as discovering drug candidates or developing formulations. Often, collaborative agreements between research organizations and large pharmaceutical companies are formed to explore the potential of new drug substances. More recently, multi-nationals are increasingly relying on contract research organizations to manage drug development.

Why are collaborative agreements important?
---
A: to explore the potential of new drug substances


Problem: Israel:

The first wave of modern Jewish migration to Ottoman-ruled Palestine, known as the First Aliyah, began in 1881, as Jews fled pogroms in Eastern Europe. Although the Zionist movement already existed in practice, Austro-Hungarian journalist Theodor Herzl is credited with founding political Zionism, a movement which sought to establish a Jewish state in the Land of Israel, thus offering a solution to the so-called Jewish Question of the European states, in conformity with the goals and achievements of other national projects of the time. In 1896, Herzl published Der Judenstaat (The State of the Jews), offering his vision of a future Jewish state; the following year he presided over the first Zionist Congress.

Who is credited as founding political Zionism?
