Consumers have reported companies targeting Ads based on their private conversation, but if you look at the number of Ads that an average consumer is exposed, it has increased from 2000 per day in 1990 to 5000 in 2018, across platforms and devices. Under such circumstances, if the technology truly exists to target based on conversation, it would be in the interest of the largest advertising companies - G and F, to offer the service to all advertisers instead of a select few.

Which of the following statement strengthens the author's position?

a) The General Data Protection Regulation (GDPR) was ...

During world war 1 and 2, the top income tax rate jumped to 77% and 94% respectively.  From 1950 to 1980, the tax rates remained above 70%. When the United States faced an unprecedented recession from July 1981, the republicans sponsored the Economic Recovery Tax Act of 1981 that cut the top tax rate to 50%.  The Tax Reform Act led by Republic president Nixon in 1986, broadened the tax based and dropped the tax rate to 28% from 1988. The recession of 1990 triggered by the Kuwait war and the Federal Reserve’s decision to hike the interest rate, pushed the republican government to increase the top income tax rate to 39.6%.

In 2013, with a slow economic recovery from the 2009 Financial crisis, the Democratic...

In Latin America, despite the growing influence of international retail chains, small independent supermarkets run by solopreneurs and traditional stores managed by families account for 45% to 61% of all consumer-goods sold. By offering coupons as credit and providing a complete shopping experience - childcare, cheaper bus service to the store, and offering personal attention, international chains could gain market share of low to middle-income Latin Americans.

For the above plan to work, what assumption do the Author most rely on?

a) The two major hurdles that are....

b) Traditional stores and supermarkets...

c) Solopreneurs and traditional....

d) The percentage of low to...

India produced a record high - more than 23 million metric ton in pulses in 2016-17. In spite of an above average monsoon and minimum droughts in the agricultural heartland, the government imported equivalent to 1/3rd of the total locally produced pulses under zero-duty imports, contributing towards drastically reducing the price of the pulses to 30% below the peak price in 2016. For Indians to have disposable income and contribute towards 8-9% annual GDP growth rate, imports of pulses should be limited?

Which statement weakens the claim of the author?

a) Agriculture contributes 17.32%....


Following the 1991 economic crash, Japan was in a two-decade stagnation, only to be revived in 2013, when the change in real GDP per working adult matched the American’s 45% over a 25-year period. The turnaround is credited to Prime Minister Abe’s aggressive money printing policy that has skyrocketed the debt to GDP ratio to 237% in 2017. Another change that set the new precedence is the increase in women representation in the working age (25 to 54-year old) that had increased from 70% in 2012 when Abe joined the office to 77.6% in 2018 – a moderate 7.6% increase that contributed the share of jobs held by 25 to 54-year old from 80.5% to an all-time high of 85.2% since the records were kept from the early 1980s.

To overcome the Opioid abuse seen in patients with chronic pain, the scientists at Stanford University have come up with a solution of silencing the neurons in the brain that register pain. The study conducted on mice along the amygdala region that is similar to humans and responsible for controlling emotions, isolated the region associated with pain from the regions responsible for negative emotions and positive rewards. However, it is the negative manifestation of the pain that protects humans from danger and fatal injuries. 

Which of the following if true most strongly supports the scientist’s argument that the...

5G technology would enable download speeds of 20 GB/second. The mammoth speed is primarily attributed to the millimeter wave spectrum that requires cellular towers every 500 feet for optimum functioning. However, scientists have raised health concerns about 5G service through the “International EMF Scientist Appeal” – a collective opinion of 215 scientists who have highlighted that the WHO have accepted the IARC (International Agency for Research on Cancer) classification of ELF EMF (Extremely low-frequency electromagnetic field) as a Group 2B carcinogen.  Even though the frequency used in 5G service is 24 gigahertz and above - similar to carcinogens like X-ray, Ultraviolet and gamma radiation, millimeter wave spectrum is...

Q) The Chorus from Sam Smith's "Stay With Me" has an eerie resemblance to Tom Petty's 1989 song - “I Won’t Back Down. Mr. Petty and Jeff Lynne, the Songwriters, filed a copyright violation case and settled out of court. Modern song creation has evolved away from the standard process - starting with the lyrics, the sheet music, and finally the tune. For new song creators, it would be impossible to fight cases where some parts of the song had similar sheet music as the songs in the 70s and 80s.

Which one of the following statements weaken the argument?

a) According to Muzic82 - an aggregated opinion database from Music Experts, 98% of the experts felt that Sam Smith's...

A newborn kangaroo, or joey, is born after a short gestation period of only 39 days. At this stage, the joey’s hind limbs are not well developed, but its forelimbs are well developed, so that it can can climb from the cloaca into its mother’s pouch for further development. The recent discovery that ancient marsupial lions were also born with only their forelimbs developed supports the hypothesis that newborn marsupial lions must also have needed to climb into their mothers’ pouches.

The argument in this passage relies on which of the following assumptions?

[A] All animals that are born after a short gestation period are born with some parts of their bodies underdeveloped.
[B] Well developed...

Set A consists of integers -9, 8, 3, 10, and J; Set B consists of integers -2, 5, 0, 7, -6, and T. If R is the median of Set A and W is the mode of set B, and R^W is a factor of 34, what is the value of T if J is negative?

(A) -2
(B) 0
(C) 1
(D) 2
(E) 5


This problem demonstrates a helpful note about statistics problems – quite often the key to solving a stats problem is something other than stats: number properties, divisibility, algebra, etc. The statistics nature of these problems is often just a way to make a simpler problem look more difficult.

Here, the phrase “factor of 34? should stand out to...

When Al Gore's 'An Inconvenient Truth' earned awards and accolades and demonstrated Global Warming as a human-induced phenomenon, not many scientists looked beyond the research papers from 'US Global Change Research Program'. The 2006 documentary was a fodder to Global Warming alarmists, who forgot the fundamental fact that the average temperature has climbed by only 1.4 degrees Fahrenheit (0.8 Degree Celsius) since global temperatures began to be monitored systematically from 1880.

The research by Andrew Dessler and his team from Texas A&M University has confirmed the previous debated theory that Water Vapor is the most contributing greenhouse gas, doubling the climate warming caused by the increased levels of...

Q) Vegan Diet proponents have often claimed that low-carb, high-fat diets integral in a non-vegetarian diet is dangerous, and therefore, they have a superior and balanced diet. In fact, vegan diets lack important nutrients, responsible for brain function and blood formation.

Which of the following statements support the conclusion of the argument?

a) Carnosine - a protective agent against aging is found only in Animal Foods.

b) Vitamin B12, found mostly in meat, and responsible for vital brain functions, is deficient in a Vegan diet with a recent study showing 92% of vegans lacking this crucial nutrient.

c) There are no conclusive studies to support the theory...

Q) If you go by the popularity of Gaming units, as of Jan 4th 2015, Sony’s PS4 sold 18.5 million units and reached 10.9 million PlayStation Plus subscribers, a growth of 37.9% from October 2014.  Despite the massive growth, Sony’s PlayStation is behind Microsoft’s Xbox One, which in November 2014 accelerated its sales due to a $50 price cut, and a bundle of free games. On 28th January 2015, Spotify, the leading music subscription service announced an exclusive partnership with PS4, and offered digital music to 64 million PlayStation Network users. With the announcement, Feb 2015 saw a spike in sales for the PS4 units by 45%.

Which one of the following conclusions is valid for the above statements...

If a and b are both positive integers, is b^(a+1) - b(a^b) odd?

(1) a + (a + 4) + (a - 8) + (a + 6) + (a - 10) is odd
(2) b^3 + 3b^2 + 5b + 7 is odd


The trick to solving this question is to remember that for positive integers:

(a) Even^(positive integer) = even
(b) Odd^(positive integer) = odd
(c) even x even = even x odd = even
(d) even – even = even
(e) odd – odd = even
(f) even – odd = odd

Using statement (1):...

GMAT Simple Interest QuestionQ) After adding a simple interest of $ 270 an investment becomes $1395. If the principal was invested at 6% p.a. simple interest, for how long was the principal invested.

A) 3 Years
B) 4 Years
C) 5 Years
D) 6 Years
E) 7 Years

Solution: As a Simple Interest problem, this question would make use of the formula,

SI = Principal * Rate * Time

Amount = SI + Principal

Plugging in values, we get,
$1395 = $ 270 + Principal

Principal = $1395 - $270 => $1125...

GMAT Critical Reasoning South Pole AssumptionIn 2013, the sea ice in Antarctica reached a record high. 80% of the increase in ice volume can be attributed to the strong westerly winds in the South Pole. The ice level is much higher than the recorded ice level during the 1970s. This proves that Global Warming is a hoax.

The argument above is based on which of the following assumptions?

a) Global warming and sea ice level are correlated.
b) Sea Ice Level in Antarctica has a stronger correlation to Global Warming
c) One of the...
