Pitcher plant is the plant that traps and feeds on the insects. This is a carnivorous plant and its leaves are called pitfall traps. The leaves are in the shape of a cup and are slippery to the sides. The leaves trench in a way that the trapped insects cannot climb out and escape. These leaves follow a prey-traping mechanism.

The Black Drongo, also known as the King Crow, is a small Asian bird of the drongo family. Previously, it was seen as a subspecies of the African Fork-tailed Drongo but is now recognised as a full species. It is a common resident breeder in much of tropical southern Asia from southwest Iran through India and Sri Lanka to southern China and Indonesia. It is a wholly black bird with a distinctive forked tail and measures 28 cm in length.
Feeding on insects, it is commonly found in open agricultural areas and light forest areas throughout its range, perching conspicuously on a bare perch or along power or telephone lines.
The species is famous for its aggressive behaviour towards much larger birds, such as crows, and never hesitates to dive-bomb any birds of prey that invade its territory. Smaller birds often nest in the well-guarded vicinity of a nesting Black Drongo.
The Black Drongo has been introduced to some Pacific islands, where it has thrived and become abundant to the point of threatening and causing the extinction of native and endemic bird species there.
Drongos fly with strong flaps of the wing and are capable of fast manoeuvres that enable them to capture flying insects. With short legs, they sit upright on thorny bushes, bare perches or electricity wires. They may also perch on grazing animals.
The Black Drongo is found predominantly in open country and usually perches and hunts close to the ground. They are mostly aerial predators of insects but also glean from the ground or off vegetation.
They are found as summer visitors to northeastern Afghanistan and northern Pakistan but are mainly resident south from the Indus Valley up to Bangladesh and into India and Sri Lanka.
Question:
Which aspect of its nature does the bird show to larger birds that attempt to violate its space?

Option 1: Its ability to fly high.

Option 2: Its tendency to sit upright on perches.

Option 3: Its ability to catch flying insects.

Option 4: Its capacity to attack.

Read the passage carefully and answer the questions that follow.
India's favourable demographic trends, which have increased the workforce's percentage of the overall population, have paved the way for a significant middle-class expansion. A big population bulge emerging from absolute poverty and set to reach the middle class would generate new dynamics. In India, over 55 percent of the population is predicted to reach the middle class. In reality, because India's demographics are significantly younger than China and the United States, the country's middle class might be the world's largest (in terms of population) by 2025.
It is no exaggeration to argue that future growth will be reliant on the increasing middle class and that the middle class's development will be reliant on growth. Growth has been fuelled by both private consumption and saving, both of which are fuelled by the middle class. India's private consumption accounts for over 60% of the country's GDP, while private consumption growth has contributed to 70% of the country's growth since 2000.
Even though China's middle class is now greater than India's, private spending in the former accounts for a lesser share of growth. In contrast to the United States, where domestic savings are dropping and the country borrows excess funds from outside to invest and expand, India's domestic savings and investments are increasing and funding investments. The emergence of the middle class is anticipated to coincide with a transition away from large-scale informality, which now characterises much of the services and industrial sectors, and toward more formal, wage-earning, and medium-scale firms. Technological advancements will spread at a faster rate. Cities will expand as the necessities concentrate on them. If there is enough movement across states and from rural to urban regions, the population increase will be more evenly distributed.

Question:
Which of the following options has contributed to the expansion of the middle class?

Option 1: Evenly distributed economic opportunities

Option 2: Increased private consumption

Option 3: Increased workforce percentage

Option 4: Increased foreign investment
