Read this text carefully. In most lines there is one word that should not be there. It is either grammatically incorrect or does not fit in with the sense of the text. Write the extra word in the box after each line. Some lines are correct. If you think there are no incorrect words in a line, write “OK” in the box. Be careful: if a line contains a word that could be removed but it is not incorrect (that is, the sentence is fine if you keep the word), then it is not wrong – you must write OK in the box.

High percentage of US patients on placebos without knowing it.

A new study amongst doctors in the United States on the use
of placebos—pills with no medical effect—which shows that almost
half of the questioned practitioners who prescribe placebos,
most of them within the last year.
The majority of 466 faculty physicians work at Chicago-area
medical schools were interviewed by a research group of the
University of Chicago stated that placebos are useful to calm and
a patient down or to respond to demands for medication that
the doctor disagrees with, i.e. "to get the patient to stop complaining".
96 percent of the physicians who surveyed believe that placebos
can have therapeutic effects. Close to 40 percent stated that placebos
could have benefit patients physiologically as well as mentally.
Twelve percent of surveyed physicians think that placebos should be
banned from clinical practice. Among the doctors who prescribed them, the
one in five said they outright lied to patients by those claiming
a placebo was not medication. But more often the physicians came up
with ways to explain like "this may help you but I'm not sure how it works."
