The correct option is "knew" because the phrase "as though" (meaning "as if") is used to describe an unreal or hypothetical situation. When the main clause verb ("acted") is in the past tense, the verb in the "as though" clause typically uses the past subjunctive to express a present or past unreality.

Here's a breakdown:

"As though" or "as if" introduces a clause that expresses an imagined or untrue condition.
When the main verb is in the past tense (e.g., "acted"), the verb in the "as though" clause should also be in a past form to maintain the sequence of tenses and indicate the hypothetical nature.
"Knew" is the simple past form, which functions as the past subjunctive in this context, indicating that her knowledge of the outcome was a hypothetical or unreal situation at the time she acted. If the hypothetical action in the "as though" clause had occurred even earlier than the main verb, the past perfect subjunctive ("had known") would be used.

For example:

She acts as though she knows the answer. (Main verb present, hypothetical present)
She acted as though she knew the answer. (Main verb past, hypothetical past/present unreality)
He talked as if he had seen a ghost. (Main verb past, hypothetical action in the past perfect)

Infinitives

Infinitives: To + verb-এর base form অর্থাৎ verb- এর present from- এর পূর্বে- to বসিয়ে infinitive গঠন করা হয়। একে Full Infinitive বলা হয়। Full infinitive-এর to অনুক্ত বা উহ্য থাকলে একে Bare Infinitive বলা হয়। যেমন—

Full Infinitive: They want to play cricket. I told him to do the work.

Bare Infinitive-They can play cricket. I heard him say this.
Note: Infinitive

Infinitive হলো verb-এর একটি Non-finite রূপ যা সাধারণত verb-এর Base form-এর আগে 'To' বসিয়ে গঠিত হয়। এটি বাক্যে একই সাথে verb এবং Noun-এর কাজ করে, তাই একে অনেক সময় 'Noun-verb' বলা হয়।

১. গঠন (Formation):

Structure: To + Base form of verb (V1).
Example: To play, To eat, To read.

২. ব্যবহারের ক্ষেত্রসমূহ:

ক) বাক্যের Subject হিসেবে:

Example: To tell a lie is a great sin.
Example: To swim is a good exercise.

খ) বাক্যের Object হিসেবে:

Example: I want to go home.
Example: She likes to dance.

গ) উদ্দেশ্য বা কারণ বোঝাতে (Infinitive of Purpose):

Example: He came here to meet me. (সে কেন এল? দেখা করতে)।
Example: We eat to live.

ঘ) Adjective হিসেবে (Noun-কে বিশেষায়িত করতে):

Example: I have no time to waste. (সময়কে বর্ণনা করছে)।
Example: Give me a chair to sit on.

ঙ) Adverb হিসেবে (Adjective-কে বিশেষায়িত করতে):

Example: English is easy to learn.
Example: I am happy to see you.

৩. Bare Infinitive (To ছাড়া Infinitive):

কিছু নির্দিষ্ট verb-এর পর 'To' উজ্জ্ব বা গোপন থাকে। একে Bare Infinitive বলা হয়।

শব্দগুলো: Bid, let, make, need, dare, see, hear, help, watch.
Example: Let him go. (Let him 'to' go হবে না)।
Example: I made him laugh.
Example: I heard him sing.

৪. বিশেষ কিছু ব্যবহার:

Too...to গঠন: He is too weak to walk.
Enough + Infinitive: He is strong enough to carry the bag.
It + Verb... + Infinitive: It is difficult to solve this problem.

৫. Gerund বনাম Infinitive:

অনেক সময় Gerund (verb+ing) এবং Infinitive (to+verb) একে অপরের পরিবর্তে বসতে পারে, কিন্তু অর্থে সামান্য পার্থক্য থাকে।

Gerund: সাধারণত কোনো সাধারণ কাজ বা অভ্যাস বোঝায়। (e.g., I like reading).
Infinitive: নির্দিষ্ট কোনো উদ্দেশ্য বা ভবিষ্যৎ কাজ বোঝায়। (e.g., I like to read this book).

৬. Split Infinitive :

'To' এবং 'verb'-এর মাঝখানে কোনো শব্দ (সাধারণত Adverb) বসানোকে Split Infinitive বলে। আধুনিক ইংরেজিতে এটি প্রচলিত হলেও ফরমাল রাইটিংয়ে এটি এড়িয়ে চলাই ভালো।

Avoid: To quickly finish.
Prefer: To finish quickly.

The basket containing ten apples were made of cane. (correct the sentence)

BCS 11th BCS Written English Subject-Verb Agreement

639

উত্তরঃ The basket containing ten apples was made of cane.

This sentence requires correction based on the principle of subject-verb agreement.

The main subject of the sentence is "The basket," which is a singular noun. The phrase "containing ten apples" is a participial phrase acting as an adjective, modifying "basket." It does not alter the number (singularity or plurality) of the main subject.

Since the subject "basket" is singular, the verb must also be singular. The original sentence used "were," which is a plural verb. It should be replaced with the singular past tense verb "was" to agree with the singular subject.

We spent the evening like in the old days. (correct the sentence)

BCS 11th BCS Written English Appropriate Preposition

735

উত্তরঃ We spent the evening as in the old days.

In formal English, the conjunction "as" is used to introduce a clause or a phrase that indicates a comparison or the manner in which something is done. In this sentence, "as in the old days" describes how the evening was spent, implying "in the way it was done in the old days."

Conversely, "like" is primarily used as a preposition to mean "similar to" or "in the manner of," and is typically followed by a noun, pronoun, or noun phrase. While "like" is often used informally in place of "as" or "as if," it is generally considered incorrect in standard written English when introducing a clause or an adverbial phrase of comparison.

For example:

Incorrect: She sings like she is a professional.
Correct: She sings as if she is a professional.
Correct: She sings like a professional. (Here, 'like' is a preposition followed by a noun phrase 'a professional'.)

Therefore, "as in the old days" is the grammatically correct and more formal choice for this context.
