Answer:
Option (d) outfile.write();
Explanation:
As the object created for the class BufferedWriter is outfile, outfile.write is the correct syntax for writing in a text file. Here, write is the method used for writing into a text file. The data present is written in the textfile. Here, the text file is opened before writing the text into the file. Option (d) is correct.
Option (a) outfile.newLine(); is used to separate the lines. This is used to break the existing lines into smaller lines. This can also be used to start a new line. Here, newLine() is the method.So, option (a) is not suitable.
Option (b) outfile.existLine(); This is not a valid syntax as there is no method called existLine() in the class BufferedWriter. So, this is a wrong option.
Option (c) Write(outfile); This is not a valid syntax for writing in a text file. This is a wrong option.
Answer:
In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.
In medical experiments, which group receives placebos?
the experimental group
the control group
both the experimental and control groups
neither the experimental nor control group
