Everyone hopes to get a job with prospects ---- promotion, but not many people manage to do so.
Correct answer is 'of'. Can you explain this answer?

Himanshu Mishra answered  •  3 hours ago
When you talk about prospects, you’re referring to the potential or likelihood of something happening — in this case, promotion.

The standard phrasing is “prospects of [something]” (e.g., "prospects of success," "prospects of improvement"), which shows the connection or possibility between the noun "prospects" and the event "promotion" .

Neither “for promotion” nor “in promo

Direction: Read the following passage and answer the question that follows:
Stacking is a familiar concept from the history of technology. When speculators laid the first railroad tracks across the United States in the early 19th century, they selected paths based on probable demand, the supply of capital, labour availability, and the contours of the landscape. If you are short on labour but long on land, it is cheaper to go around the mountain than to dig a tunnel through it. When the next set of network builders strung telegraph cables, it made sense to run them along the railroad tracks: the equipment could be easily transported, and railroads were major users of telegraph signals to coordinate traffic. John Gast’s classic painting American Progress (1872), of American appropriation of Native American lands through settlement, shows the connection clearly. Guess what path the major internet cables follow? There are clear reasons for stacking technological systems: shared expertise, economies of scale, distribution of consumers, etc. It is not, however, a widely appreciated phenomenon in intellectual history. Sometimes, the stacking of fringe theories is pretty straightforward. Believing that Earth is flat and that the Apollo 11 Moon landing in 1969 was faked on a soundstage are conceptually distinct beliefs. Nothing about the latter impels you to believe the former. However, believing that Earth is flat essentially requires that you think that NASA’s achievements are part of an elaborate conspiracy: there is no ability to travel to the Moon, nor are the photographs of a globular Earth from space authentic. These fringe theories stack through logical interconnection. Fringe doctrines can also share a political sensibility. The mid- to late-19th-century enthusiasm for spiritualism – communication with ethereal spirits by groups of individuals seated around a séance table in a dimly lit room – tracked with socialism, women’s suffrage and vegetarianism. All were heterodox theories concerned with liberating the oppressed.

A supermarket has to place 12 items (coded A to L) in shelves numbered 1 to 16. Five of these items are types of biscuits, three are types of candies and the rest are types of savouries. Only one item can be kept in a shelf. Items are to be placed such that all items of same type are clustered together with no empty shelf between items of the same type and at least one empty shelf between two different types of items. At most two empty shelves can have consecutive numbers.
The following additional facts are known.
  1. A and B are to be placed in consecutively numbered shelves in increasing order.
  2. I and J are to be placed in consecutively numbered shelves both higher numbered than the shelves in which A and B are kept.
  3. D, E and F are savouries and are to be placed in consecutively numbered shelves in increasing order after all the biscuits and candies.
  4. K is to be placed in shelf number 16.
  5. L and J are items of the same type, while H is an item of a different type.
  6. C is a candy and is to be placed in a shelf preceded by two empty shelves.

There are 5 types of biscuits, 3 types of candies and 4 types of savouries. Among 16 shelves, there are 4 empty shelves.
It is given that all items of same type are clustered together with no empty shelf between items of the same type.
From (3) and (4), it can be concluded that D, E, F and K are savouries.
From (2) and (5), L, I and J are of one type and H is the other type. Therefore from (6), as C is a candy, L, I J must be types of biscuits and H is a type of candy. Now using (1), we can conclude that A and B are of one type but not candies as there are only 3 types of candies.
Therefore,
Biscuits: A, B, I, J, L Candies: C, H, G Savouries: D, E, F, K
From (3), (4), (6) and (7), there shelf number 12 must be an empty shelf. Also, D, E, F and K are placed in shelves numbered 13, 14, 15 and 16 respectively.
Now from (1), (2) and (7), the sequence (from left to right) in which biscuits are kept is:
(Empty shelf), L, A, B, (I/J), (J/I).
From (6), the candies must be in the following order: (Empty shelf), (Empty shelf), C, (H/G), (G/H)
Thus, we have
In the second case we have shelf 1, 2, 6 and 12 empty.
Hence, option (c).

A supermarket has to place 12 items (coded A to L) in shelves numbered 1 to 16. Five of these items are types of biscuits, three are types of candies and the rest are types of savouries. Only one item can be kept in a shelf. Items are to be placed such that all items of same type are clustered together with no empty shelf between items of the same type and at least one empty shelf between two different types of items.

In each case, J and I can be arranged in 2 ways and G and H can be arranged among them in 2 ways. Thus, 2 × 2 = 4 ways.
Total number of ways the items can be arranged on the shelves = 4 + 4 = 8
Kiran Basak asked a question

Passage: Over the past decade, there has been a significant shift in the global economic landscape. Economists and policymakers are grappling with the fallout of a post-industrial economy, where traditional manufacturing jobs have dwindled due to a combination of outsourcing, automation, and evolving economic policies. This change has left a vast section of the population, once reliant on these sectors, struggling to find stability in the new economic order.
Simultaneously, the rise of the digital economy has created unparalleled opportunities for a different segment of the workforce. These opportunities, however, require a skill set that is markedly diverse from what was necessary in the past. The rapid pace of technological advancement means that professional success in the current context often depends on one's ability to adapt and learn continuously.
This economic polarization has led to societal repercussions, contributing to widening income inequality. Researchers have observed this phenomenon in multiple countries, noting that the middle class, once the backbone of the economy, is shrinking. The wealthy continue to amass significant capital, particularly those strategically positioned to benefit from digital advancements, while the lower-income segments face stagnation.
The government's role in addressing these shifts remains a topic of intense debate. Some argue for more significant intervention, including re-education programs, subsidies for industries negatively impacted by the changes, and more progressive taxation to redistribute wealth more equitably. Critics of this approach, however, caution against excessive government involvement, pointing to potential dampening effects on innovation and economic freedom.
Amid these debates, one emerging consensus is the need for a robust support system to facilitate lifelong learning and skill acquisition. This approach is not without challenges, as it necessitates a fundamental rethinking of societal structures, including education and social safety nets. The goal would be to empower individuals to navigate these economic shifts proactively, rather than being passively subjected to the whims of global market forces.

Read the passage carefully and answer the following questions:
Five years ago we launched the Simons Foundation Powering Autism Research for Knowledge (SPARK) to harness the power of big data by engaging hundreds of thousands of individuals with autism and their family members to participate in research. The more people who participate, the deeper and richer these data sets become, catalyzing research that is expanding our knowledge of both biology and behavior to develop more precise approaches to medical and behavioural issues.
Genetic research has taught us that what we commonly call autism is actually a spectrum of hundreds of conditions that vary widely among adults and children. Across this spectrum, individuals share core symptoms and challenges with social interaction, restricted interests and/or repetitive behaviours.
We now know that genes play a central role in the causes of these “autisms,” which are the result of genetic changes in combination with other causes including prenatal factors. Essentially, we will take a page from the playbook that oncologists use to treat certain types of cancer-based upon their genetic signatures and apply targeted therapeutic strategies to help people with autism.
But in order to get answers faster and be certain of these results, SPARK and our research partners need a huge sample size: “bigger data.” To ensure an accurate inventory of all the major genetic contributors, and learn if and how different genetic variants contribute to autistic behaviours, we need not only the largest but also the most diverse group of participants.
The genetic, medical and behavioural data SPARK collects from people with autism and their families is rich in detail and can be leveraged by many different investigators. Access to rich data sets draws talented scientists to the field of autism science to develop new methods of finding patterns in the data, better predicting associated behavioural and medical issues, and, perhaps, identifying more effective supports and treatments.
Genetic research is already providing answers and insights about prognosis. For example, one SPARK family’s genetic result is strongly associated with a lack of spoken language but an ability to understand language. Armed with this information, the medical team provided the child with an assistive communication device that decreased tantrums that arose from the child’s frustration at being unable to express himself.
SPARK has identified genetic causes of autism that can be treated. Through whole exome sequencing, SPARK identified a case of phenylketonuria (PKU) that was missed during newborn screening. This inherited disorder causes a buildup of amino acid in the blood, which can cause behaviour and movement problems, seizures and developmental disabilities. With this knowledge, the family started their child on treatment with a specialized diet including low levels of phenylalanine.
We know that big data, with each person representing their unique profile of someone impacted by autism, will lead to many of the answers we seek. Better genetic insights, gleaned through a complex analysis of rich data, will help provide the means to support individuals—children and adults across the spectrum—through early intervention, assistive communication, tailored education and, someday, genetically-based treatments. We strive to enable every person with autism to be the best possible version of themselves.
Q. Which of the following cannot be inferred?
I. The effectiveness of 'big data' is determined not by its size but by its diversity.
II. Genes are a major factor influencing autism.
III. Consumption of a diet containing low levels of phenylalanine helps decrease the level of amino acid in the blood.

Mahesh Mehta asked a question

A shopping mall has a large basement parking lot with parking slots painted in it along a single row. These slots are quite narrow; a compact car can fit in a single slot but an SUV requires two slots. When a car arrives, the parking attendant guides the car to the first available slot from the beginning of the row into which the car can fit.
For our purpose, cars are numbered according to the order in which they arrive at the lot. For example, the first car to arrive is given a number 1, the second a number 2, and so on. This numbering does not indicate whether a car is a compact or an SUV. The configuration of a parking lot is a sequence of the car numbers in each slot. Each single vacant slot is represented by letter V.
For instance, suppose cars numbered 1 through 5 arrive and park, where cars 1, 3 and 5 are compact cars and 2 and 4 are SUVs. At this point, the parking lot would be described by the sequence 1, 2, 3, 4, 5. If cars 2 and 5 now vacate their slots, the parking lot would now be described as 1, V, V, 3, 4. If a compact car (numbered 6) arrives subsequently followed by an SUV (numbered 7), the parking lot would be described by the sequence 1, 6, V, 3, 4, 7.
Answer the following questions INDEPENDENTLY of each other.
Suppose that car 4 is not the first car to leave and that the sequence at a time between the arrival of the car 7 and car 8 is V, 7, 3, 6, 5. Then which of the following statements MUST be false?
