Both A and R are true and R is the correct explanation of A

B

Both A and R are true but R is not a correct explanation of A

Consider the relational schema given below, where eId of the relation dependent is a foreign key referring to empId of the relation employee. Assume that every employee has at least one associated dependent in the dependent relation. Employee (empId, empName, empAge) Dependent(depId, eId, depName, depAge) Consider the following relational algebra query: ΠempId(employee)-ΠempId (employee⋈(empId = eID)∧(empAge ≤ depAge)dependent) The above query evaluates to the set of empIds of employees whose age is greater than that of

A

some dependent.

B

all dependents

C

some of his/her dependents

D

all of his/her dependents

Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Read the statements and choose the correct answer:
Assertion (A) The nominal interest rate comprises of a real interest rate and an expected rate of inflation and it adjusts when the inflation rate is expected to change. Hence, in the perfect international capital markets, real rate of returns are equal in the two countries.
Reason (R) The international fisher effects states that the nominal interest rate differential must be equal to the expected inflation rate differential In the two countries.

A

Both (A) and (R) are correct and (R) is the right explanation of (A)

B

Both (A) and (R) are correct, but (R) is not the right explanation of (A)

C

(A) is correct, but (R) is not correct

D

Both (A) and (R) are incorrect

Analysis of a hexapeptide using enzymatic cleavage reveals the following result:
• Amino acid composition of the peptide is: 2R, A, V, S, Y
• Trypsin digestion yields two fragments and the compositions are: (R, A, V) and (R, S, Y)
• Chymotrypsin digestion yields two fragments and the compositions are: (A, R, V, Y) and (R, S)
• Digestion with carboxypeptidase A yields no cleavage product.
Given: Trypsin cleaves at carboxyl side of R. Chymotrypsin cleaves at carboxyl side of Y. Carboxypeptidase A cleaves at amino side of the C-terminal amino acid (except R and K) of the peptide.
The correct amino acid sequence of the peptide is:

A

RSYRVA

B

AVRYSR

C

SRYVAR

D

SVRRYA

Assertion (A): Generally, validity of the test is dependent upon the reliability
Reason (R): A test which yields inconsistent results cannot be expected to correlate with outside independent criterion
