XAT 2014 — VARC Question 6
Read the definitions below and select the best match between the numbered sentences and the definitions.
Premise: A proposition from which another statement is inferred or follows a conclusion.
Assumption: Something, which is accepted as true.
Facts: Something, which can be checked.
Reason: A cause, explanation or justification for an action or event.
Conclusion: An end, finish or summarization of process or argument.
Proposition: A statement that expresses judgment or opinion.
Question: A sentence worded or expressed so as to elicit opinion.
Inductive inference: An end, finish or summarization reached for “the whole”, based on “a particular” real incidence.
Deductive Inference: An end, finish or summarization reached based on the combining and recombining two or more than two assumptions.
Read the following sentences and choose the option that best arranges them in a logical order.
Choose the best option:
- The mechanism of electroweak symmetry breaking is one of the most important issues in the present Particle Physics.
- They are required to give masses for all quarks and leptons and to guarantee the absence of the gauge anomaly.
- In the standard electroweak model a fundamental Higgs doublet is introduced to cause the spontaneous symmetry breaking.
- Supersymmetry (SUSY), eliminating all quadratic divergences, may provide a better theoretical basis to describe a fundamental Higgs boson with a relatively small mass to a high energy cutoff scale, say the Planck scale for example.
- In the minimal SUSY extension of the standards electroweak model the Higgs sector consists of two chiral superfields of Higgs doublets (H1 and H2 with opposite hypercharges).

1, 5, 2, 3, 4

The paragraph is on the concept of electroweak symmetry and the role of the Higgs doublet in it. Statement 1 makes for a suitable introduction since it introduces the concept of “electroweak symmetry” in the context of Particle Physics. This eliminates options 3 and 5.
Statement 1 is followed by statement 3 which tells us why a Higgs doublet is introduced with regard to the electroweak model mentioned in statement 1. Eliminate options 2 and 4.
Statement 4 follows statement 3 by introducing the concept of Supersymmetry(SUSY) which is referred to in its abbreviated form in the rest of the sentences.
Statement 5 follows statement 4 by linking SUSY with the electroweak model and introducing the concept of two chiral superfields.
The relative pronoun “they” in statement 2 refers to the same chiral superfields, lending an apt conclusion to the paragraph.
Thus, the correct sequence is 1, 3, 4, 5, 2.
Hence, the correct answer is option 1.
