Research shows that when people work with a positive mind-set, perform

A.Two people with the same genetic make-up and environment can have different happiness quotients.
Incorrect: Can be Inferred
This statement follows from the first sentence of the second paragraph. The author states that even though our genetics and our environment have an impact on how happy we are, our general sense of well-being is surprisingly malleable.
The author goes on to elaborate on the “malleable” part by describing how we can manage our happiness by things that are in our control. Accordingly, even if the genetic and environmental factors are kept constant for two individuals, their attitude can influence their individual happiness quotients.
B.For happiness to result from success, the latter needs to be a stationary target.
Correct
In the first paragraph, the author states that the happiness that results from success is fleeting or shortlived as success is a moving target. This clearly suggests that even when success is not a stationary target, happiness is possible- albeit shortlived.
C.Increment in remuneration is not the only important factor responsible for improving the performance of employees.
Incorrect: Can be Inferred
This statement can be derived from the last sentence of the passage in which the author states that encouraging employees to accept some level of stress as an inevitability and perceive it as motivator and a fuel to growth is vital for boosting the performance of the workforce.
D.Some factors beyond that we have little control over impact how happy we are.
Incorrect: Can be Inferred
The author contrasts our genetics and our environment with other factors that are within our control. So, it can be inferred that our genetics alongwith our environment are pitched as those that we have little control over.
E. The order in which success and happiness occur is not necessarily fixed.
Incorrect: Can be Inferred
In the first paragraph, the author talks about how people do not really understand the relation between success and happiness and then cites the example of the order of success and happiness that most people believe in to illustrate this point. Clearly, this choice follows from there.

The first paragraph explains the relationship between cultivating a positive outlook and professional success while the second paragraphs shows how happiness and success can be achieved. The correct answer must take in to account the main idea of both these paragraphs.

A.showing how happiness can be cultivated rather than passively experienced
Incorrect: Partial scope
This choice captures the scope of only the second paragraph.
B.guiding employers with respect to increasing the overall happiness and success quotient of the employees
Incorrect: Partial scope
The author does talk about boosting employee performance in the last sentence of the passage but nowhere else in the passage does the author make any other suggestions to employers as such.
C.clarifying why happiness is not dependent on factors other than a positive outlook
Incorrect: Inconsistent
The author does talk about the link between happiness and positive outlook in the second paragraph but at the same time agrees that our genetics and environment affect how happy we are. Hence, there are other factors as well that determine happiness.
D.proposing that happiness and the resultant success at work are rather dependent on our attitude
Correct
This choice is on the lines of our pre-thought answer. It combines the scope of both the paragraphs.
E.outlining the ways in which one can achieve professional success
Incorrect: Partial scope
While this choice does almost cover the scope of the first paragraph, it does not take in to account the author’s main point in writing the first paragraph.

A.Most people use success to measure their happiness.
Incorrect: Out Of Scope
The author says that most people think success comes before happiness and not that they use it as a tool to measure happiness.
B.Even when the situation is tough, a positive outlook can trick the brain in to believing otherwise.
Incorrect: Out Of Scope
Although the author does state that a positive outlook helps perform better in the face of an obstacle/challenge, there is no mention of how the same is achieved- whether by tricking the brain our changing the way we perceive the challenge is not discussed. However, given the contents of the passage, it is most likely in the latter way.
C.One of the most important ways of boosting employee performance is encouraging them to accept some level of stress as a part of the job.
Incorrect: Out Of Scope
The author does consider it an important way but there is no information given on whether it is one of the “most important” ways.
D.Developing common habits with coworkers can help reduce stress significantly.
Incorrect: Out Of Scope
Habits and interactions with co-workers are listed as two separate aspects and the author does not build or indicate towards a combination of the two.
E.When happiness is triggered by success, it is anything but everlasting.
Correct
This statement states the same thing as the following statement made by the author in the first paragraph:
but, because success is a moving target, the happiness that results from success is fleeting.
