It should be C and F

The answer is C and F.

Concur means agree. Has no sense in the economy of the sentence.

Can anyone explain why not predict ?

When you have to deal with a secret code you do not PREDICT the code.

You cannot decipher the code and do not RECOGNIZE the plan made behind it.

but we decipher a code . So shouldnt the answer be decipher for first blank

Same question, if you have received the British message but cannot decipher it, then you cannot recognize the enemy plans.

this isn't ETS material?

This is NOT ETS material for sure.

Sorry, I wrote above wrong

This is a two-blank text completion question that tests:
- Historical Context: Understanding WWII codebreaking (e.g., Enigma, British ciphers).
- Vocabulary: Words like "decipher," "extrude," and "concur" must fit the military context.
- Logical Flow:
- Blank (i): The Nazis' failure to crack British codes.
- Blank (ii): Their resulting inability to anticipate/discover enemy plans.

Approach:
1. Blank (i): "Unable to [blank] British code..."

(A) extrude (force out) $\(\rightarrow\)$ Nonsensical for codes.
(B) decipher (decode) $\(\rightarrow\)$ Fits; Nazis couldn't break the cipher.
(C) predict $\(\rightarrow\)$ Incorrect; codes are decoded, not predicted.

2. Blank (ii): "...despaired of being able to [blank] the plans."

(D) hackneyed (overused) $\(\rightarrow\)$ Irrelevant; not a verb.
(E) concur (agree) $\(\rightarrow\)$ Incorrect; unrelated to discovering plans.
(F) recognize $\(\rightarrow\)$ Partial fit, but "anticipate" or "divine" would be stronger.

Correct Pair: (B) decipher, (F) recognize.
