'Gregor Mendel in examining tea-plants found two sharply marked races, the tall
and the short. He experimentally fertilized flowers of tall plants with pollen of short. The off
spring were tall plants. He next let the flowers of this first generation be fertilized with their
own pollen. In the following generation, shortness reappeared. Tallness and shortness were
distributed not at random but in a definite, constant, and simple ratio: three dominant tails to
one recessive short'. Which one of the following aptly describes the distribution of dominant
and recessive characteristics ?

• systematic

• equal interval

• unpredictable

• irregular interval

'Perhaps the earliest work of Archimedes that we have is that on 'Plane Equilibrium'. In
this, some fundamental principles of mechanics are set forth as rigorous geometric propositions.
The work opens with famous postulate 'Equal weights at equal distances are in
equilibrium; equal weights at unequal distances are not in equilibrium, but incline toward
the weight at the greater distance'.
According to this passage, which factor or factors determine equilibrium ?

• weight

• distance

• weight & distance

• equality of weights & distances

A college received fifty applications for a certain course. In the qualifying examination, one-tenth of them secured marks in 90-95% range. Within remaining segment, threefifths of them secured marks in 75-90% range. The rest secured below 75%. To get admission, the following restrictions hold good

• No student who has scored below 75% can seek admission to Physics course.

• No student is allowed to opt Physics without opting Mathematics

• No student is allowed to opt Physics and Astrophysics simultaneously

• To opt Mathematics or Astrophysics, a student should have scored at least 70% in the qualifying examination
