The correct answer is (A) is true but (R) is false.
Key Point
  • (A) Earthworm is referred to as a farmer's best friend.
    • This statement is true.
    • Earthworms are considered beneficial for agriculture because they play several crucial roles in soil health and plant growth:
      • Aerating the soil: Earthworms burrow through the soil, creating tunnels that allow air, water, and roots to penetrate deeper.
      • Improving Drainage: These tunnels also improve drainage and prevent waterlogging, which can harm plants.
      • Enriching the soil: Earthworms feed on organic matter and their castings are rich in nutrients like nitrogen, phosphorus, and potassium, which improve soil fertility.
      • Promoting microbial activity: Their activities stimulate the growth of beneficial soil microbes, further contributing to soil health.
  • (R) Earthworms destroy the weeds.
    • This statement is false.
    • While earthworms can indirectly affect weed growth by improving soil conditions that favor desirable plants, they do not actively seek out and destroy weeds.
    • They feed on organic matter, which includes decaying plant material, not living plants like weeds.
Therefore, 
(A) is true but (R) is false.

Read the given passage and answer the following questions.The debate about how much screen time we should have is pretty common these days. On one hand, there's a huge positive side to being online. It's great for keeping up with friends who don't live close by and for finding out all sorts of interesting stuff. Who hasn't fallen down a Wikipedia hole or learned something cool from a YouTube tutorial? Plus, for a lot of people, social media is a way to speak up about things they care about, reaching loads of people without needing a ton of resources.However, there's the other side of the coin. Ever noticed how sometimes, after scrolling through social media for a while, you don't feel that great? Some say that constantly comparing ourselves to the perfectly posed snapshots of others' lives can make us feel pretty down. And then there's the whole thing about getting stuck in our own little bubbles, only hearing opinions that echo our own, which doesn't really help us grow or understand the world better.So, what's the best path forward? It's tricky. No doubt, the internet and social media have their perks, making our lives more connected and insightful in ways we couldn't have imagined before. But it's also clear that too much of anything isn't good. Finding a balance—where we make the most of what the digital world offers without letting it take over our real-life connections or sense of self-worth—is the key. How we strike that balance, though, looks different for everyone, and it's something we're all figuring out together.Read the following sentences:Reason: Being online has both positive and negative effects. Assertion: The passage suggests finding a balance in using digital platforms is essential.
