arr[1] = scan.nextInt();
arr[2] = scan.nextInt();
arr[3] = scan.nextInt();
System.out.println("Contents: " + arr[1] + " " + arr[2] + " " + arr[3]);
int Sum = (1 + 2 + 3);

Answer:
Clara should use computer lenses and artifical tears.
The computer lenses help block blue light from entering your eyes which would help with the headaches and help you focus on something further away. The artificial tears help lubricate dry eyes which prevents or in Clara's case, reduces/relieves eye strain.

B. False.
Explanation:
Cryptanalysis can be defined as the study, art or process of evaluating and analyzing information systems such as ciphertext, cryptographic systems and ciphers. The main purpose of Cryptanalysis is for a better understanding of how the cryptographic system works, in order to find techniques for deciphering, defeating or weakening them without an access to any privileged or secret data (information) required to do so.
Hence, cryptanalysis is made more difficult by having longer keywords as opposed to having shorter keywords which typically would make it easier for an attacker to decipher.
In a nutshell, it is false and incorrect to say that cryptanalysis is made more difficult by having shorter keywords.
