Research is commonly divided into "applied" and "pure". This classification is arbitrary and loose, but what is usually meant is that applied research is a deliberate investigation of a problem of practical importance, in contradistinction to pure research done to gain knowledge for its own sake. The pure scientist may be said to accept as an act of faith that any scientific knowledge is worth pursuing for its own sake, and, if pressed, he usually claims that in most instances it is eventually found to be useful. Most of the greatest discoveries, such as the discovery of electricity, X-rays, radium and atomic energy, originated from pure research, which allows the worker to follow unexpected, interesting clues without the intention of achieving results of practical value. In applied research it is the project which is given support, whereas in pure research it is the man. However, often the distinction between pure and applied research is
A. the investigation of the life cycle of a protozoon is pure research.
B. applied investigation is looked down upon in modern society.
C. the discovery of X-rays was made in applied research.
D. the common classification of research is neither accurate nor impersonal.

A. The author first refutes the classification of research into the pure and the applied and then analyze the reasons for the intellectual snobbery and tendency to look down on the one of the two.
B. The author first refutes the classification of research into the pure and the applied and then presents his own classification.
C. The author first refutes the classification of research into the pure and the applied and then points out that the classification results from two false ideas.

"Worse than useless," fumed Darrell Issa, a Republican congressman from California, on March 19th, when the House Judiciary Committee held a hearing on the Immigration and Naturalization Service. "Terrible, and getting worse," added Zoe Lofgren, a Democratic colleague who has kept a watchful eye on the INS for ten years.
Committee members lined up to take swings at James Ziglar, the head of the INS. He explained, somewhat pathetically, that "outdated procedures" had kept the visa-processing wheels grinding slowly through a backlog of applications. He also had some new rules in mind to tighten up visas. Speeding up the paperwork -- and getting more of it on to computers -- is vital, but the September attacks have exposed the tension between the agency’s two jobs: on the one hand enforcing the security of America’s borders, and on the other granting privileges such as work permits to foreigners.

A. charges launched against its head.
B. its merging with the Customs Service.
C. other security recommendations.
D. its separation into two bodies.
