Q:

Read the passage carefully and select the best answer to each question out of the given four alternatives.

 

By practicing mindfulness and other principles, we become more aware of and present to our fears and others’ fears, bearing witness as a way of healing and empowering. We see the spiritual path as intertwined with the path of social action, with contemplation and action parts of the same whole, each nourishing and guiding the other. Acknowledging that our well-being depends on others makes caring for others’ well-being a moral responsibility.


Through a “mindful citizen” exercise, we create a story articulating who we are as individuals who are also part of communities. This exercise helps us move beyond cynicism, complacency, and despair, instead infusing us with a sense of purpose. We embrace our gifts, resolving to do our part to promote a sense of common humanity as a means toward social justice.


With this exercise, I believe we can help students bridge their divides and replace anger and distrust with compassionate connections – just as I witnessed between Shirley and Tiffany.


Shirley returned to class after a brief hiatus, keeping a cool distance from Tiffany. But over the weeks spent together they gradually came to know each other. They practiced seeing and listening, sharing stories so different that they felt bewildered as to how they could overcome the gap. But they found that acknowledging their differences led them to discover a place of deep connection in commonalities, such as being raised by grandmothers, and even wounds, including childhood trauma, that they never imagined existed.


In assessments of these classes, students say that these small groups become “healing communities,” where we overcome victimization and claim agency. Healing occurs as we transcend an “us vs. them” mentality, crossing borders and forging connections. These communities show a way of reducing intergroup prejudice and fostering inclusion based in psychology research and pedagogical practice.

 

How students can replace their anger and distrust?

A) With the help of compassionate connections. B) By diverting their mind.
C) By going into deep meditation. D) By doing some physical exercise.
 
Answer & Explanation Answer: A) With the help of compassionate connections.

Ants have been living on the earth for more than 100 million years and can be found almost anywhere on the planet. It is estimated that there are about 20000 different species of ants. For this reason ants have been called Earth's most successful species. If you watch ants for any length of time you will see that they really do communicate with each other and very effectively too. Ants communicate by touching each other with their antennae. Ants also use chemicals called pheromones to leave scent trails for other ants to follow. Ants build many different types of homes. Many ants build simple little mounds out of dirt or sand. Other ants use small sticks mixed with dirt and sand to make a stronger mound that offers protection from rain. Western Harvester ants make a small mound on top, but then tunnels up to 15 feet straight down to hibernate during winter. Ant mounds consist of many chambers connected by tunnels. Different chambers are used for nurseries, food storage, and resting places for the worker ants. Some ants live in wood like termites. Army ants don't make a home at all but travel in a large groups searching for food. Ants are social insects which means they live in large colonies or groups. Some colonies consist of millions of ants. There are three types of ants in each species, the queen, the sterile female workers and males. The male ants only serve one purpose, to mate with future queen ants and do not live very long. The queen grows to adulthood, mates, and then spends rest of her life laying eggs. A colony may have only one queen, or there may be many queens depending on the species. Ants go through four stages of development: egg, larva, pupa and adult.

 

What is the purpose of male ants ?

A) To lay eggs B) To protect the colony
C) To mate with future queen ants D) To live a long life
