3842. Read the passage and answer the question. In medical research, patients who are given a 'dummy' pill containing no active drug sometimes report that they feel better. This is known as the placebo effect. It appears to be strongest for symptoms such as pain and tiredness, which are influenced by a person's expectations. For this reason, new medicines are tested against a placebo: a drug is considered effective only if it works better than the dummy pill. Why are new medicines tested against a placebo?

      कBecause placebos have no effect at all खTo show that the medicine works better than expectation alone गBecause placebos are cheaper to produce घTo find out which patients are honest

Which study method is best supported by Ebbinghaus's findings?

      कLearning only meaningful words खStudying all night before a test गReviewing material several times over a period of days घReading material once very carefully

3848. Read the passage and answer the question. Natural rubber becomes sticky in hot weather and hard and brittle in cold weather, so early rubber products were not very useful.

      कRubber was too expensive to collect. खRubber could not be heated. गRubber was too heavy for tyres. घRubber changed too much with temperature.

This idea later spread to the Arab world and then to Europe, where it changed the way people did arithmetic. What was Brahmagupta's contribution, according to the passage?

      कHe wrote rules for using zero in calculations. खHe invented the symbol for an empty space. गHe brought zero from Europe to India. घHe proved that zero is not a real number.
