Question : The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
He does not / know how to / draw quickly / and straightly.
Option 1: and straightly
Option 2: He does not
Option 3: know how to
Option 4: draw quickly
Correct Answer: and straightly
Solution : The first option is correct.
Explanation: The adverb form of straight is straight, not straightly. Adverbs are often formed by adding -ly to adjectives, but straight is an exception. It remains the same when used as an adverb.

Question : Comprehension: Read the following passage and answer the questions given after it. The severe cyclonic storm, Nisarga, which made landfall south of Alibag in Maharashtra’s Raigad district on Wednesday at 11.30 a.m. is an indication of an increasing frequency of severe cyclones developing in the Arabian Sea in the past decade, a trend that studies have linked to climate change. In the past two years, there have been seven cyclones in the Arabian Sea, though, according to the India Meteorological Department (IMD), the ratio of cyclones in the Arabian Sea and the Bay of Bengal — which just witnessed the destructive cyclone Amphan on May 21 — is 1:4. The Intergovernmental Panel on Climate Change (IPCC) last year came out with a special report, Ocean and Cryosphere in a Changing Climate, in which it said that extreme rainfall and extreme sea level events associated with some tropical cyclones are being seen to have a cascading impact on coastal areas. “There is emerging evidence for an increase in the annual global proportion of Category 4 or 5 tropical cyclones in recent decades,” the IPCC report had said. A category 4 cyclone has a wind speed of 209-251 kmph, and is referred to as an extremely severe cyclonic storm, while a category 5 cyclone has a wind speed of more than 252 kmph, and is referred to as a super cyclone. The IPCC report refers to a 2017 study led by the Atmospheric and Oceanic Sciences Program, Princeton University, USA, which found that in 2014 and 2015, post-monsoon extremely severe cyclonic storms (ESCS) were first observed over the Arabian Sea causing widespread damage. The study had concluded that climate change had led to an increase in the occurrence of ESCSs in the Arabian Sea.“Our research suggests that cyclones would be more frequent during the post-monsoon season (October-December) by a series of climate model simulations. However, we didn’t find any significant changes in cyclone activity during the pre-monsoon (April-June) season through the climate simulations. It is very difficult to identify if a cyclone (like Nisarga) is generated in line with climate change,” said Hiroyuki Murakami, the lead author of the study. “Coastal hazards will be exacerbated by an increase in the average intensity, magnitude of storm surge, rising mean sea levels and precipitation rates of tropical cyclones,” the IPCC report further stated. Question: Match the words (a, b, c) with their meanings (1, 2, 3). a. cascading 1. intensify b. precipitation 2. drop-down c. exacerbate 3. rainfall

Question : In a triangle ABC, the three angles are $x, y$, and $y+10$. Also, $2x-4y=20^{\circ}$. Which type of triangle is ABC?
Option 1: Equilateral
Option 2: Obtuse
Option 3: Acute
Option 4: Right-angled
Correct Answer: Right-angled
Solution : In a triangle ABC, the three angles are $x,y$, and $y+10$. Also, $2x-4y=20^{\circ}$ The sum of all angles of a triangle is $180^\circ$ $\therefore$ $x+y+y+10=180^{\circ}$ ⇒ $x+2y = 170^{\circ}$.............(1) Given that, $2x-4y=20^{\circ}$.........(2) Solving the above two equations by performing 2(equation 1) + (equation 2), we

Question : A boat moves 25 km upstream and 39 km downstream in 8 hours. It travels 35 km upstream and 52 km downstream in 11 hours. What is the speed of the stream if it travels at a uniform speed?
Option 1: 4 km/hr
Option 2: 5 km/hr
Option 3: 6 km/hr
Option 4: 3 km/hr
Correct Answer: 4 km/hr
Solution : Let the speed of the boat be $x$ and that of the stream be $y$. According to the question, $\frac{25}{x-y}+\frac{39}{x+y}=8$ ----------------- (1) $\frac{35}{x-y}+\frac{52}{x+y}=11$ ----------------- (2) Multiplying equation (1) by 4 and equation (2) by 3 and then subtracting equation (2) from (1), we get,
