Q:

Some hills are rivers. Some rivers are desrets. All desrets are roads.

Conclusions:

1. Some roads are rivers

2. Some roads are hills

3. Some deserts are hills

A) None follows	B) Only 1 follows
C) Only 1 and 2 follows	D) All follow

Answer & Explanation Answer: B) Only 1 follows

Explanation:

Some hills are rivers. Some rivers are deserts.

Since both the premises are particular, no defenite conclusion follows.

Some rivers are deserts. All deserts are roads

Since one premise is particular,the conclusion must be particular and should'nt contain the middle term. Since it follows that 'Some rivers are roads'. 1 is the converse of this conclusion and so it holds.

Q:

What are the blocking and non-blocking assignments in Verilog and which is preferred in Sequential Circutis?

Answer

A blocking assignment is one in which the statements are executed sequentially, i.e., first statement is executed and variable is assigned a value then second is executed and so on. A non blocking assignment is one in which statements occurs conturrently, only non blocking assignments should be used in sequential circuit.

e.g.

initial

begin

a=b; //blocking

c<=a; //nonblocking

d=c; // blocking

end

In this example firstly the value of b is assigned to a and this value is assigned to c only after execution of first statement. the second and the third statements are executed simultaneously, i.e. value a ais assigned to c and previous value if c is assigned to d.

Q:

All snakes are trees. Some trees are roads. All roads are mountains.

Conclusions:

1. Some mountains are snakes

2. Some roads are snakes

3. Some mountains are trees

A) Only 1 follows	B) Only 2 follows
C) Only 3 follows	D) Both 1 and 2 follow

Answer & Explanation Answer: C) Only 3 follows

Explanation:

All snakes are trees. Some trees are roads.

Since the middle term is not distributed even once in the premises,so no conclusion follows

Some trees are roads. All roads are mountains

Since one primise is particular,the conclusion must be particularand should'nt contain the middle term. So,it follows that 'Some trees are mountains'. 3 is the converse of this statement and so it holds.

All snakes are trees. Some trees are mountains.

Since the middle term is not distributed even once in the preises, so no definite conclusion follows
