There has been much speculation concerning the origin of lunar craters. One hypothesis is that they are the result of the impact of heavy meteors on the surface of moon while still soft. The most probable explanation is that they were produced by the gases liberated from the rocky matter. "While solidification was taking place these gases and water vapors steadily escaped through viscous surface, raising giant bubbles. The reader can easily visualize the process that took place by watching frying of pancakes. Which one of the following actually helps us to determine the origin of lunar craters?
“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 furious postulate ‘Equal weights at equal distances are in equilibrium; equal weights at unequal distances are not in equilibrium, but incline towards the weight at the greater distance.’
According to this passage, which factors determine equilibrium?
According to the passage, assign a truth value to: “Unequal weights at equal distances are in {disequilibrium.”}
According to the passage, assign a truth value to: “Unequal distances are in {disequilibrium.”}
A tourist must tour {four} places out of $A,B,C,D,E,F,G$. At most two can be {holiday} places and at least two must be {business} places. Types: $A,B,C,D$ are Business; $E,F,G$ are Holiday. Rules: (a) If $A$ is included, then both $C$ and $G$ are excluded. (b) If neither $E$ nor $F$ is included, then $B$ or $G$ or both may be included. (c) If $G$ is included, then $D$ cannot be included. Which combination is {possible}?
A college received fifty applications for a course. In the qualifying exam, $\tfrac{1}{10}$ of them scored $90$–$95%$. Of the remaining, $\tfrac{3}{5}$ scored $75$–$90%$; the rest scored below $75%$. For admission the rules are:
(i) no one below $75%$ can join {Physics};
(ii) {Physics} cannot be opted without {Mathematics};
(iii) {Physics} and {Astrophysics} cannot be taken together;
(iv) to opt {Mathematics} or {Astrophysics} one must have at least $70%$.
Which alternative is {possible}?
Many environmentalists are inconsistent: progress without some interference with nature is a myth, yet environment includes animal wealth too, so we must ask whether we may kill living beings (even harmful insects/stray dogs) merely for hygiene. Which one of the following runs {counter to the spirit of the passage?}
It is said that in his strongly worded reaction to quantum Physics, Einstein remarks ‘God does not play dice’ to which Bohr, another great physicist, reacted saying ‘Do not tell God what to system, though we can know the properties of macrocosmic objects.
A moot question to be considered is whether democratic form of government is boon or bane, no matter what Lincoln might or might not have said. Rather his most (in?) famous adage, ‘by the people, for the people and of the people’ misses the most pertinent question; which attitude works behind when a person declares that he is a (or the right?) candidate to serve the people, and does not hesitate to contest and fight tooth and nail the election, an euphemism for battle with or without bullets. Admittedly, the convert attitude is different from overt attitude. Hardly anyone contests the election unwillingly. A contestant is not persuaded by any one, but driven by his own passions and dubious motives. Contrast this picture with Socrates' version; no honest man willingly takes up the job of ruler. If at all he accepts, he does so for fear of being ruled by one made up of inferior mettle. It is beyond even the wildest imagination, to expect an honest person to contest the election. Assuming that every statement is true, identify from among the given alternatives the one which strictly follows from the passage.
Gregor Mendal 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 offspring 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 talls to one recessive short. Which one of the following aptly describes the distribution of dominant and recessive characteristics?
Four members are to be nominated to a Committee from six candidates $A,B,C,D,E,F$. Rules:
(A) If $A$ is nominated, then $D$ is excluded.
(B) If $B$ is nominated, then exactly one of $E$ or $F$ must also be nominated.
(C) If $C$ is nominated, then both $D$ and $B$ must be nominated. Which set of four is possible?
(Same set-up as Q.152, but with {additional} restrictions stated in the original question.) Which one of the following is a {certainty?}
