Option 3 : Nylon

The correct answer is nylon.

Concept:

Waste materials: 

  • Waste materials are either liquid or solid in form, and their components may be either hazardous or inert in their effects on health and the environment.
  • The term waste is typically applied to solid waste, sewage (wastewater), hazardous waste, and electronic waste.

Explanation:

Biodegradable Waste Non-biodegradable Waste
The substances that can be decomposed by the action of decomposers like bacteria and fungi. The substances that can not be decomposed by the action of decomposers like bacteria and fungi.
For example organic matter like human excreta, animal waste, dead bodies of plants and animals, leftover food items, natural fabrics like cotton, wool, etc. wood, paper, grass, and so on. 

For example plastic, 

rubber, glass, artificial clothes like nylon, rayon, electronic waste like batteries, etc.

Thus,

  • Grass - Biodegradable
  • Paper- Biodegradable
  • Nylon - Non-biodegradable
  • Wood - Biodegradable

Consider the following solution to the producer-consumer synchronization problem. The shared buffer size is . Three semaphores empty, full and mutex are defined with respective initial values of 0, and 1. Semaphore empty denotes the number of available slots in the buffer, for the consumer to read from. Semaphore denotes the number of available slots in the buffer, for the producer to write to. The placeholder variables, denoted by P, Q, R, and S, in the code below can be assigned either empty or full. The valid semaphore operations are: wait ( ) and signal ( ). Producer: Consumer: do {         wait (P) ;         wait (mutex) ;         //Add item to buffer         signal (mutex) ;         signal (Q) ; } while (1) ; do {          wait (R) ;          wait (mutex) ;          //Consume item from buffer          signal (mutex) ;          signal (S) ; } while (1) ;   Which one of the following assignments to P, Q, R and S will yield the correct solution?

In making decisions about important questions, it is desirable to be able to distinguish between ‘strong’ arguments and ‘weak’ arguments. ‘Strong’ arguments are those, which are both important and directly related to the question. ‘Weak’ arguments are those, which are of minor importance and also may not be directly related to the question or may be related to a trivial aspect of the question. The questions below is followed by two arguments numbered I and II. You have to decide which of the arguments a ‘strong’ argument is and which a ‘weak’ argument is. Statement: Should plastics be banned completely Arguments: I. Yes. All the types of plastic are non-biodegradable. II. No. Some plastics can be recycled and used again. A complete ban is not necessary.  ?
