Two processes X and Y need to access a critical section. Consider the following synchronization construct used by both the processes Process ? /* other code for process ? */ while(true) { varP = true; while(varQ == true) { /* Critical Section */ varP = false; } } /* other code for process ?? */   Process ? /* other code for process ? */ while(true) { varQ = true; while(varP == true) { /* Critical Section */ varQ = false; } } /* other code for process ? */   Here, varP and varQ are shared variables and both are initialized to false. Which one of the following statements is true?
From an alloy, two specimens are machined and tested separately under tension and compression. The engineering stress-strain curves as well as the true stress-true strain curves for tension and compression are plotted in the same diagram. Identify the correct statements:
P. The engineering stress-strain curves in tension and compression are identical.
Q. The true stress-true strain curve in compression is lower than the true stresstrue strain curve in tension due to Bauschinger effect.
R. The true stress-true strain curve in tension is above the corresponding engineering stress-strain, curve.
S. The true stress-true strain curve in tension and compression are identical.
A woman is considered to be in labor when she begins experiencing regular uterine contractions, accompanied by changes of her cervix – primarily effacement and dilation. While childbirth is widely experienced as painful, some women do report painless labors, while others find that concentrating on the birth helps to quicken labor and lessen the sensations. Most births are successful vaginal births, but sometimes complications arise and a woman may undergo a cesarean section. What inferences can be drawn from the above paragraph?
If while packing of jams, the temperature is too high, they thicken to a large extent and then they’re difficult to remove.
Consider the following threads, T1, T2, and T3 executing on a single processor, synchronized using three binary semaphore variables, S1, S2, and S3, operated upon using standard wait() and signal(). The threads can be context switched in any order and at any time. T1 T2 T3 While(true) { Wait(S3); Print(“C”); Signal (S2); } While(true) { Wait(S1); Print(“B”); Signal (S3); } While(true) { Wait(S2); Print(“A”); Signal (S1); }   Which initialization of the semaphores would print the sequence BCABCABCA….?

Consider the following proposed solution for the critical section problem. There are n processes: P0…Pn – 1. In the code, function pmax returns an integer not smaller than any of its arguments. For all i, t[i] is initialized to zero. Code for Pi: do {                 c [i]=1; t[i] = pmax (t [0],…, t[n-1]) +1; c[i]=0;                 for every j ≠ I in {0,…,n-1} {                                 while (c[j]);                                 while (t[j] != 0 && t[j]<=t[i]) ;                 ]                 Critical section;                 t[i] =0;                 Remainder Section; } While (true); Which one of the following is TRUE about the above solution?
