A lie detector finds out that the subject is telling a lie______.
A．by detecting and analyzing the subject's physical changes
B．by increasing the subject's pulse rate, sweating and breathing rate
C．by analyzing the answers on the subject to certain questions
D．All of the above
A．Because lie detection is surrounded by uncertainties
B．Because it restricts the defendants' rights to prove that they are innocent
C．Because 12 states also allow lie detection evidence to be heard in courts
D．Because federal judges from the Supreme Court make their decisions on the basis of lie detection evidence
Uncertainties surround the science of lie detection, which uses a device called polygraph. In 1991 President George Bush banned lie detector evidence in military courts. But that ban has since been overturned by the U.S. Court of Military Appeals, which ruled that it restricts defendants' rights to present evidence of their innocence.
In the past two years, some federal courts have also ruled that polygraph evidence can be heard. This follows a decision by the Supreme Court in 1993 that gave federal judges more discretion to decide on the admissibility of evidence.
A polygraph consists of monitors for pulse rate, sweating and breathing rate. The device is supposed to uncover lies by recording increases in these measures as the subject answers questions.
Critics have always argued that cunning defendants can control their physiological responses and sway polygraph results. But supporters of the technique argue that recent research has found it to be reliable. A psychologist named Charles Honts at a state university in Idaho, points to lab oratory studies, some of them being his own, in which student-subjects were offered cash to sway the test results.
This argument is rejected by Leonard Saxe, a psychologist at a Boston university. "There is a huge difference between students in a lab and a defendant", he says. Guilty defendants have time in which to rehearse their lies, and can even come to believe them to be true.
Saxe believes that the entire theoretical basis of lie detection is invalid. "It assumes you will be more nervous lying than telling the truth". But he says that for some people lies are trivial, while certain truth can be hard to swallow.
David Faigrnan of the University of California says that if the Supreme Court upholds the military appeal court's decision to allow polygraph evidence, polygraph bans would be overturned in federal courts across U.S. "That will put a big burden on judges to understand the science, and lead to a lot more' expert testimony in the courts", he predicts. The justice department fears that this will greatly increase the cost of trials.
According to the passage, which organization raised the proposal to stop the practice of lie detection evidence in military court？
A．Federal Government.
B．U.S. Supreme Court.
C．Department of Justice.
D．Military Courts.

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)
The burning of two black churches in Clarendon county, S.C, last year may be a case of extremist terrorism. Clarendon county Sheriff Hoyt Collins said Welch was carrying a membership card for the Christian knights of the KKK when he was arrested. Federal authorities are considering civil-rights charges against them, and FBI agents are investigating the possibility that the Clarendon county arsons are connected to other church fires.
The reality is that the federal task force is entering a quagmire. Arson is always a tough crime to investigate, and the evidence in many of these cases is getting old; some may never be solved with some 300,000 churches nationwide, there are approximately 600 cases of arson against church buildings every year. The overall trend is down, although not among black churches in the rural South. Many of these churches are older wooden buildings—tinder-boxes located on country roads miles from police and fire departments. They are extremely vulnerable to arson and, because they burn so quickly, often destroy evidence of the crime as well.
The black clergy who descended on Washington a week ago are deeply skeptical of ATF. One reason is that ATF agents who know from experience that about half of all arsons are inside jobs—have questioned and in some cases polygraph black churchmen search of leads. "they strapped a lie detector on me and asked me if I burned the church", says Harold Smith, assistant pastor at the Inner city in Knoxville, Tenn. "When your life is in the ministry.., it hurts to be asked questions like this". Aggressive investigative tactics have already led to trouble at the top. Told that federal prosecutors had subpoenaed some black clergymen in a search for inside suspects, Attorney General Reno reportedly blew her stack and ordered to top-level summit meeting to set limits on the field agents tactics.
As administration officials struggled to meet Clinton's declared goal of bringing racially motivated arsons to a halt, new fires destroyed black churches in Charlotte, North Carolina, and Greenville, Texas. These fires inspired White House aides to scramble Clinton's travel schedule to allow the stop in Green Leyville, South Carolina—where Clinton, in his familiar role as the nation's consoler-in-chief, delivered a moving speech at the dedication of a black church that was burned out last year. But even Jackson acknowledged that Clinton must walk a fine line.
Too much crusading by this president could prompt even more arsons by the loose cannons of the ultra right. Given the weird admixture of racism and simple loneness that lay behind these crimes, prayerful caution—and even a measure of forgiveness—seemed the wisest stance. "We want the world to know we are not angry with anyone", said Rev. A. Baldwin, summing up the tragedy, in Enid "we are a loving church. But it just broke my heart."
It can be inferred from the para. 1 that ______.
A．the Clarendon county are connected to other church fires
B．the burning of churches may be caused by terrorists
C．no one was arrested
D．FBI agents are not involved in the case
I found him ______on the ground.
